MTN still has me jumping through hoops

Good day, It seems the only way that I get any sort of response is if I make a noise on Social Media!! I have tried to pay my account since the beginning of the month (after the Debit Order was deducted from the wrong account where there weren't funds - as per my previous complaint on here, which was finally resolved I hope), but there were no details on any of my invoices, and according to the MTN 'mycontract' website my account is closed. Last statement available March 2020. PLEASE RECTIFY!

As a desperate attempt to pay my account, as my service has been suspended (Imagine how quickly that happened, but trying to get hold of anyone on 135 is impossible), I have made a payment with my cell number as my reference. My reference number is included to assist with allocation of the funds, as my cell number is the only reference that Standard Bank would allow as a reference to MTN Postpaid Contract Beneficiary Account. Someone please call to sort out my Account ASAP to ensure that I can pay via the wonderful (not really) MTN App or the MyContract Website.
