MTN disaster

In November '22, we approached MTN to transfer my personal account with 5 numbers to a business account owned by my wife. As I live in Ballito we did this through the Ballito MTN shop at the local mall. we dealt with Justin and after a lot of communication and submittance of all financials, id's bank account details we awaited the transfer to occur. It is now June '23 and all that has happened is one of the 5 numbers has detached itself from my account and an invoice is now sent separately, for that number, however the transfer has not happened and I'm now at my wits end. Can MTN please contact me and get this sorted out please. thank you. Jerod Flaum
