Money Account Payment Reversal Not Updated

Good Day Peter I have an Old Mutual Money Account. I am happy with their service to a certain point. When you pay the prebeneficiaries on the mobile app it takes nearly 2 weeks for the client to update their payment. The proof of payment does not reflect the reference number even though it is entered when making payment. About nearly two months ago on 27th Sept 2019 I made two payments to multichoice using the money account app but I used the incorrect account number. To this day nobody from old mutual can advise me where is my money. All I get is that they cannot reverse payments to corporate accounts. I paid R319.00 twice to the incorrect account andI understand that the typo was my fault, but where is this money when the account number is incorrect and the client obviously cannot trace this amounts in their accounts. R638.00 might not seem alot to Old Mutual but it is to me as I have to make up for this amount. They do not respond to me when ask where is this money and I am being ignored now, perhaps to them this query is solved, but how? Which account was this paid to when it is the wrong account number. I am so disappointed in this company and their service.
