Funds reversal complaint

My tenant was transferring money into my bank account and unfortunately chose an incorrect option.He instead used the pay to cell option.I did receive an sms but was not sure how to access the funds.I visited the local fnb branch and they put me through to their call centre.After being sent from one consultant to the was ultimately told the money would be back in the senders account within 3 to 5 days,that never happened.We went back to the branch and again put through and I had to listen to music for 33 minutes. I gave up and went back the following day,again listen to music for 40 minutes and then was asked to rate the service without anyone answering the phone.The branch official phoned herself and after some time was told we need to fill in a reversal form and we did as the money went into my old fnb credit card account which I closed about 6 years ago.I no longer bank with fnb closed all my accounts due to their service.I now got an email to say the form must be sent to a different email to the one on the form.I now don't know what else to do as I have beentransferred to so many divisions since the 4th of January 2023
