Missing Payment - 8 Months

I was supposed to receive a payment of R10 000into my FNB account on the 15th February 2021 to date i have not received the payment. I have made contact numerous amount of times and went it to the branch, no one has knowledge of the FNB products as a whole which is really disturbing as being employees of FNB. FNB keeps saying they cannot see if a payment was supposed to be made to my account and that the receipient has to call in . the recipient sending from standard bank has provided proof of payment and spoke to fnb tracing depart which said the transaction was successful which is not true. I have been provided a Retrieval Reference Number (RRN) FROM FNB TRACING DEPARTMENT yet fnb says there is nothing they can do with that number.
