Go to the hell you and your bank app

This is, without a doubt, the worst banking app and the worst customer service experience I have ever had.

Someone used my KAST card for unauthorized subscription charges. Instead of protecting me or resolving the issue quickly, my account ended up with a negative balance, and I was left dealing with constant declined transaction notifications.

What disappointed me the most is the customer support. I explained my situation multiple times, waited for weeks, and had to keep chasing them just to get a reply. Every response felt automated, and no one actually solved my problem.

The worst part is that I decided to close my account, but they won’t even let me do that. They keep asking for more information while my account remains open. It honestly feels like they’re making it unnecessarily difficult for customers to leave.

A bank should make customers feel safe and supported, especially when fraud happens. Instead, I felt ignored, frustrated, and trapped.

I have completely lost my trust in KAST. I would never recommend this app to anyone. If you value your money, your time, and responsive customer support, stay away from this service. It has been one of the most disappointing financial experiences I’ve ever had.

Account locked

After changing my phone number I lost my access, had multiple emails with support - all lead to the same reply without follow up. Had a chat with support, send 3 different photo verification, all at day time with everything clearly visible and readable, now asked for video selfie with both hands on the video and “small conversation “. If you have nerves, to receive reply from concierge at 11pm with request of small video of you, while you deal with em all day with delay in replying for hours…. It’s sooooo frustrating and annoying. It’s like they take pleasure to keep asking for the same thing all over again again and again. I wanna scream and I wanna sleep at 11pm and not chatting about accounts, because on US time - they support is at sleep apperently. Going to go to atm tomorrows morning and take my money and not dealing with this nincence

I am honestly at a loss

I've been one of KAST's top ambassadors since early on, and I never expected to be writing this. My account has been frozen with no clear explanation, after everything I've put into this project.

I've referred nearly 2,000 users to KAST. I've earned almost $70,000 in KAST Points and generated close to $5,000/month in referral commissions — all built through genuine effort, not gaming the system. I've spent countless hours creating content about KAST that ranks on Google, writing reviews and articles that helped real people discover and trust the platform. That content is also widely referenced by AI models — ask an AI about crypto cards and KAST often comes up, partly because of what I've written.

Last year the Etherfi team reached out about me joining them. I turned it down because I believed in KAST and the value I was building here.

So finding my account frozen, with no clear reason given, has been genuinely disappointing. I'm not asking for special treatment — just a fair, personal review of my case. If this is how KAST treats one of its biggest ambassadors, it's worth asking what that means for everyone else putting in real work to support this platform.

I'm hoping someone at KAST reviews this properly and helps get my account restored. I'd rather this end with a resolution than with me having to update my reviews to reflect what's actually happened. 🙏

Thank you for everything you’ve contributed to KAST and for sharing your concerns. We understand how disappointing this situation must feel. Our team is already working on your case and reviewing it carefully. Please stay connected with our support team for updates.

Scamming you with massive fees

Fx fees are overtaking cashback. And cashback is even a bet on a future valuable equity. Avoid this card issuer and use something more transparent. U are also selling your coins the moment u deposit into kast which is a taxable event! I am not saying any competitor is better but Kast is really bad

Response from developer

We’re sorry to hear this. We aim to keep fees and rewards clear, and we understand your concern about FX costs and cashback value. You can review our fees here: https://www.kast.xyz/legal/fees. KAST does not provide tax advice, but we encourage users to review their own tax obligations. If you need more help, please contact our concierge team.

Account blocked with no reason

If you intend to use the account be aware that Kast can lock you out from our own account if you receive above some specific amount . I understand the reasons the do this but this should be clear to the user wich actions he needs to do before making the deposit not after receiving it. It would save a bad review and my time (and I’m not talking about millions of dolars …..)

Response from developer

We understand your concern. For security and compliance reasons, account reviews may be triggered by different factors, not only the amount received. We agree the process should be clearer, and we’re working to improve this. If you need help with your case, please contact us at support@kast.xyz.

KYC chaotique, zero transparence

À éviter si vous recherchez un processus KYC sérieux. Mon dossier a été traité par plusieurs interlocuteurs avec des demandes incohérentes, des exigences qui changeaient constamment et aucune explication claire sur les rejets répétés de mes documents. Après avoir transmis plusieurs documents personnels sensibles, j’ai perdu toute confiance dans leur procédure. Une expérience très décevante!

Financial Freedom

I love the freedom of spending stablecoins everywhere I travel. I love the slick user experience. I love the cashback, especially as a Premium Member.

Highly recommend

After I got referred by BELUGA, I realised how easy Kast made it to spend

The did Swift go?

I used to be able to transfer money to my us account until Swift disappeared. Why?

Blocked by the update

I’m almost every month blocked to use the app because they update and require to update the app as mandatory. I would rather make it optional or enable to keep using the app even if it’s not updated. Sometimes my internet is not good and I’ve to do the financial operation and I can’t. So I can’t rely on Kast, it will f. me at least one time.

Response from developer

We’re sorry for the frustration. We understand mandatory updates can be inconvenient, especially when your internet connection is limited and you need to access the app urgently. Some updates are required for security, reliability, and important fixes, but we’ll share your feedback with the team about making updates less disruptive where possible. If you’re blocked again, please contact support at support@kast.xyz so we can help.

Response from developer

A KAST já pagou milhões em indicações e recompensas. A maioria dos usuários participa corretamente e recebe os pagamentos. No entanto, identificamos cerca de 3.000 contas gerando atividade falsa e retivemos pouco mais de US$ 100.000 em recompensas relacionadas. Se você está indicando pessoas reais que realmente usam a KAST, não há com o que se preocupar. Se precisar de suporte ou tiver alguma dúvida, entre em contato com nossa equipe em support@kast.xyz.

Too many updates

Stop pushing your damn app every single day Jesus ChrisT. I just wanna check my balance. I don’t wanna upload a new app every single time I look at it
