I made an immediate payment from my Discovery Bank account to my FNB account at 09:02, and the funds have still not reflected. It is extremely disappointing that, instead of resolving this matter promptly, I have been subjected to ongoing back-and-forth with no accountability or clear outcome. I have already lodged a complaint, which has not been attended to. This level of service is unacceptable. I expect this matter to be resolved immediately and my funds to be made available without any further delay. Should this not be resolved urgently, I will have no choice but to escalate this matter to the relevant regulatory bodies.
