Bad service

On the 8th of November 2021 I did a transfer from nedbank to Tyme Bank. 2 days later I realized that the money has not reflected. On Monday I called nedbank to check why the money have not cleared they told me that the money was transfered successfully. That was strange because the money had not reached to my account. I asked the Nedbank consultant to check the account no I used when I did a transfer. Only to found out I used the wrong acc no. I tried to get my money or ask the bank to reverse the money with no luck. I am very angry that they couldn't help me. In future the banks should have do reversals for transfers. Now I have lost 5000 for my rent money. I guess if there all form was done immidiately without waiting 7 days maybe I could have found my money. I blame the bank for not reversing my money. At this point I think I should cancel my account wt nedbank and open another account with another bank
