It is very common sometimes when we trade on exchange p2p payment delays,  these delay can be from the buyer's bank or seller bank's.  Many people have lose their money due to this delay of bank network thinking that the problem of the delay is from the network of bank which they will later get their money when the network of their bank becomes good and they go ahead to release the payment because of  evidence of payment that the other trader have sent to show as proof.

I had trade to sell bitcoin in an exchange and I was matched with a buyer, so after he did the bank transaction I was waiting to get bank alert and the amount of money in my account Balance.  We both complained to the exchange customer service to help how to go about the issue and the buyer was asked to submit his statement of account which he did,  he brought evidence of payment that made it looks as if the delay of payment that have not reached me was from me. With every I was still not ready to release the payment it reflect in my account,  this issue last about more than 30 hrs abd and the following day I sent him a message to contact his bank the delay which he said he did.

It wasn't up to 10 minutes after he contacted his bank I received the payment in my account.  If I had release the payment because of the pressure of customer service in the exchange,  the money wouldn't have gotten to me, which the buyer will be nowhere to find to make complains to his bank . Beginners should never make mistakes to release no matter how long it takes for them to receive payment.  Hold on till everything is settled from both sides.
