Poor service I want to move to a better bank with better service

Received a payment of R13600 from Nedbank on Friday 21 November 2025 and all the payments he made on that day was flagged from Nedbank, the person who made a payment called Nedbank ***** diversion to advise that the all the transactions were legitimate. Then Nedbank removed a hold on his account and the told him they have sent an email to discovery bank to remove a lock on the funds that were flagged but discovery bank is refusing to do so. I’ve been calling my bank and it seems like they not willing to lift a finger for me as their client. It’s end of the month I needs my funds to cover my expenses. So I would like discovery bank to release all my funds in all my accounts I have with them then will move to a better bank. Very poor service from discovery bank. They didn’t even give me a reference number
