***** on MTN contract

I have been trying for over a year to resolve ***** on my 83 year old Mothers account. Emails, phone calls, advocate affidavits, police affidavits, several trips to log, relog and follow up on the requests at the Cresta branch only to have each logged request closed without resolution and no logical reason as to why from MTN. Recent debits coming through on her bank account for thousands of Rands worth of data not ordered by my Mother - a true disgrace if this is how MTN treats its longstanding and loyal elderly customers. The final straw happened today - they suspended her service creating huge anxiety for her as her cell phone is her means of communication with the outside world despite MTN owing her money for data and a device she never ordered or received!
