I read these accusations, but personally, I can not take anyone's side in this issue. The user was not informed in advance, but he also made a mistake by sending a fake. In addition, there are many accusations against Binance, Coinbase etc, but many people use them without problems. Choosing ChangeNOW I evaluated the quality of this service first of all. I made several exchanges to check out, I'm not new to this. I carefully read their terms of use. I really liked ChangeNOW, and it doesn’t matter to me that someone had problems with them, especially since he received a refund. If it were otherwise, it would be a real scam.
