I've been trading in Binance P2P for many years now, I don't encounter such issues. I don't think if it's just in your Country, because here in my place all is well in terms of P2P trading. Binance provided an instruction how to post an ad and they provide the criteria how to become a verified merchant. And because what I'm doing is to withdraw from them, I just need to find an ad. And since your problem is about the bank you're using, try to make up with another banks because afaik there are lot of method to send the payment.
