AGGRAVATING MATTER (REFUND NOT RECEIVED FROM FNB AFTER OVER A MONTH

I have tried to obtain a refund that was accidentally paid to me by someone else on the 25th May 2022, refund request form submitted on the 2nd JUNE 2022 but to date nothing has been done other than emails sent back to back from the digital department that is also unable to help. I fully completed a refund form as per instructions received and sent it back to FNB. I was told to send it back and will receive the refund in the account after 10 days. Its been over a month now no refund but the R325 for the service has been charged on the persons account who paid the money to my account. I spoke to the following people who keep referring the matter to other departments Aletha Visser, Rachel Masoma & Molakeng Maneo.
