Not assisting customers with there problem. 3 months later and still nothing has been done

<p>My husband upgraded his MTN contract in November 2015 for the amount of R419.00. From then the problems started. Every month they were deducting R635. I think 3 of 4 months ago he went in to MTN Fleurdal and they passed a credit and said the problem was fixed. 2 months later they deducted R1050.00 and we went in again and sent a e-mail to MTN customer care to try to assist him to get the problem fixed, but the consultant asked for a letter giving me permission to get the information. I got the letter form my husband that he signed and it was sent to customer care. Then suddenly the letter was not right, so she asked that he must go to the police station to write a affidavit and then they can give me the information. This month the account is almost R1000.00 again and when my husband phoned customer care yesterday, they said that it is because of a compitition that he has entered that make the amount that high. The thing that we can not understand is that since the upgrade we did not received the invoices + the itemized billing, but we pay for it. So the account is high and we do not know what is the reason for it. How can it take a company almost six months to short out a problem.</p> <p>This is really the worst service we ever received.</p>
