Perfeito para minhas viagem

I had a very unpleasant experience with KAST

The payments themselves worked, although their FX costs are extremely high; in my experience, more than 3%. I was willing to accept that because KAST advertised 1.5% cashback. I used the card, spent money, and the cashback kept accumulating. However, I was unable to actually use or withdraw the rewards. When I contacted support, I was told that I had to wait a month. I wasn’t in any financial difficulty, so I didn’t really care. I assumed the reward would eventually become available.

It didn’t.

After the reward continued to accumulate without being paid out, I contacted them again. After around 10 days of back-and-forth communication, I was eventually told that, according to their Terms, I wasn’t eligible for the reward because I hadn’t followed the rules. That was extremely frustrating. If there are conditions that determine whether a customer receives the advertised reward, those conditions should be made clear before the customer spends money expecting to receive it.

I eventually gave up, stopped using KAST, and switched to Ether.fi. My experience there has been dramatically better. More importantly, the EUR/USD exchange rate I was getting through Ether.fi was around 0.87 compared with roughly 0.84 through KAST. That difference alone is roughly a 3% advantage — effectively more than the cashback KAST was offering, without having to deal with a cashback program at all.

My main concern, however, isn’t even the cashback. It’s the experience of giving a company custody/access to your money and then having difficulty getting the rewards you were led to expect, followed by a 10-day support discussion about Terms and eligibility. Based on my experience, I personally would avoid KAST. I would be particularly cautious about keeping significant amounts of money with a financial company until I was completely comfortable with its terms, operations and the people/entities behind it.

There are alternatives that, in my experience, provide a much better overall proposition.

"Horrible automated system and unhelpful support"

"I have never opened an account with this app before. During my first registration attempt, their automated verification system rejected my identity documents by mistake. When I contacted customer support, they offered no help, shared no reasons, and just told me the decision was final before closing the chat. Very poor experience for new users. Do not recommend."

Account blocked after asking for help

I contacted KAST only to change the Apple Private Relay email linked to my account.

Instead of fixing a basic account issue, support sent me through repeated identity checks, recovery questions, device checks and transaction verification.

I provided everything they asked for. There was no fraud, no unauthorized access and no compromised account.

KAST then blocked my account while I was still trying to resolve the issue with support.

I had already tried to fix the same email problem in January and eventually gave up.

A financial service that handles your money must have support that can solve basic account problems without turning them into a security incident.

Terrible experience, I do not recommend it

I tried to receive a SWIFT transfer with KAST and it was rejected. I submitted all the supporting documentation they requested, and they assured me everything was fine and told me to try again. I did, and not only was the transfer rejected a second time, but they also deducted $25 from the returned amount. They never refunded that money and, despite multiple complaints and follow-ups, they never gave me an answer or a concrete solution.

Waste of time

I tried it about a year ago and got the same response every single thing is valid my documents the id the address I even asked if u need any additional documentation or information how come it didn’t work I just signed up for a ADIB bank about a week ago why didn’t they say im unable to process I never even got to experience the app I tried it the first time to sign up after waiting 1-2 days i got the same Response now with the same wait and actually needed the app in this moment i got the same response what is this????? At this point im just deleting the app. This is unacceptable This doesn’t even deserve a 1 star This is my first time ever writing a bad review for an app how come a manual review of my documentation fail it would've been reasonable if it was done by an ai even an ai accepts it after the first try and this took about 48 hours. What an absolute waste of time I could’ve looked for an other app by that time

Simo

My experience with Kast has been extremely frustrating. They announced a 10% cashback campaign from June 15 to July 31 for payments made with the Kast card on Meta and TikTok ads. I made nearly $4,000 in eligible transactions during the campaign, yet I received no cashback.

When I contacted support, they asked me to provide the transaction IDs. However, I discovered that these transactions had disappeared from my Kast transaction history, even though they are still clearly visible in my Facebook payment history from the same period. It appears that Kast removed the transactions from its own history, making it impossible for me to provide the IDs and claim the cashback I was promised.

This is extremely disappointing and feels completely unfair. I fulfilled the campaign requirements, and I expect Kast to investigate the missing transactions and honor the 10% cashback offer.
I’m not using this Bank again.

Hi Simo, we’re sorry for the frustration. Please contact us at support@kast.xyz with the email linked to your KAST account and any Meta/Facebook payment screenshots showing the dates, amounts, and merchant details. We’ll investigate the missing transactions and cashback eligibility. If the payments meet the campaign terms, we’ll work to resolve this accordingly.
