Why am I not receiving my funds? Poor services.

On the 8th May 2022, I made an ATM deposit at 1 of the ATM @Brits Mall. But I didn't receive a notification on my decice. I then realized I had made a deposit into a wrong account. I tried calling help desk but got an automated responses I couldn't find a consultant to make the query. I went to the Brits mall Branch when I had the chance, which was in Wednesday, was given a form to request funds reversal, promised it would be sent through and shod expect a call to request further details if need be. I even logged the query on the Banking app. To this day, I had received no communication regarding my query. No reference, no call, No email, No communication of any sort. I expect a response to say the funds I had deposited were secured pending investigations, but I guess I should say FNB is waiting for the account owner to use those funds and for FNB to tell they couldn't refund me? Why do we trust the institution with our funds which obviously the staff members don't care if they are safe or not? At this point, i have no evidence I logged the query at the branch. I'm afraid I might jit get those funds back, generally I'm not sure anymore to trust FNB with holding the account. This is poor service, it shows lack of safety and that if our funds are credited into wrong accounts, they don't care. As long as they get to charge their transactional fees. I'm ****ed off. Why is your rating even 4.1/10? Shameful for a banking institution.
