A nightmare

Blocked a US businesses operating for two decades from making calls to U.S. clients. After “verification”. No due diligence.. We never called a client or lead who did not share the number with us on purpose. No support, just more stupid excuses and questions.

Account restrictions may require additional checks even after verification. Please contact support@zadarma.com from your registered email address so we can review the restriction and clarify the next steps.

Verification delay

I am a new customer, and I was so happy to know that I was finding a way to receive from call from US from a land phone to a new US number is very important to me that I receive these calls, however, after seeing that prices changed, depending the plan, I was OK with that and I decide to do a three months plan which I was charged before they verify my ID. It’s been days and I’m still waiting for the verification of my ID, having very slow response actually none just one saying that my verification is been waiting, so it will be nice if they verify the ID before making the payment as the days keep counting and I still don’t have a response of my verified ID and no, I really customer service where I can talk to

Номери, які вони продають для 70% клієнтів на холодні дзвінки, вони захистити від спаму не можуть, бо ти маєш згоди від власника номеру на який дзвониш, і все. Клоуни

Quality and customer service

This isn’t worthy the hassle and quality of calls very poor.

Quality of calls terrible, when calling an international destination from the U.S., I can speak to the person on the other line for like a minute after that it replays what the other person on the line said during that minute and keeps on replaying that on repeat (as if that was recorded). Only way to get around it was to hang up and call again. Other issue also when calling sometimes it connects to wrong numbers on the other end, not the actual number I was calling.

Additionally contacting customer service via chat wasn’t helpful. Took couple weeks for verification and when contacted customer service via chat, the person didn’t want to help basically kept on repeating the same sentence over and over as if it was a computer responding, and wasn’t interested in understanding the issue. Only after sending another email I was cleared/“verified” for international calls.

Response from developer

Thank you for sharing your experience — we’re sorry to hear about the difficulties you faced. Call issues like audio looping or incorrect call routing are not expected behavior and usually require a technical check on our side. The same applies to delays during verification — we understand how frustrating that can be, especially when international calls are involved. To properly review what happened with your calls and the verification process, please contact us again at support@zadarma.com or open a ticket via https://my.zadarma.com/tickets/ and include the call examples (dates, times, and numbers). This will allow our technical team to investigate the issue in detail and provide a clear resolution. Support ticket.

The worst virtual number service

I verified my account, rented a number but I didn't receive any SMS from Instagram. I wrote to support and they refused to refund me or change number. I just lost my money!
