Mistakes so costly - CPC Department service is awful and really frustrating

REFERENCE NO *** SR Ref No : ***9 A month ago I realised I made an error of making a payment to Standard Bank for a closed credit card account I had and I asked the team to kindly assist me to transfer this payment to another institution in South Africa. ZAR 3092.16 was provided with the proof of payment on March 4 2016 was paid in error to my closed credit card account. I was given instructions by Christine Salman to write a letter on April 13, requesting the funds to be transferred to the third party which I did. I have sent numerous enquiries via email , calls and have been given many variations of whether this has happened. I received an email from Warren Dix indicating the transfer of the credit was done on April 19, 2016 and when I called to ask for the proof I spoke to someone in the customer care today 3 May who says it was done 28 April. PLEASE ALL I NEED IS A CONFIRMATION THAT THE TRANSFER WAS DONE SO I CAN TELL THE THIRD PARTY TO GO AHEAD AND CHECK FOR RECEIPT. Best
