MTN MAKING CUSTOMERS PAY FOR THEIR INTERNAL ERRORS

My elderly mother has a contract with MTN which she pays R160 a month for. She's a 77 year old pensioner. Last month she received an sms from mtn asking her to approve a new sim cars request on her account. She did not reply to the sms so no approval was given by her for this sim card. For reasons that have still not been explained somebody at mtn went ahead and approved the new sim card which was then used to wrack up an additional almost R700 in charges even though we called mtn as soon as we got the sms about the sim card and we were assured that the sim had been blocked. We even sent an affidavit pet request stating that the sim card request did not Cole from my mother. To our shock and surprise instead of debating the usual R160 from my mom's account this month an amount of over R800 was debited to cover the additional charges. We called the ***** department and we're advised to reverse the debit order and then do an eft payment for the normal R160. Today my mom received an sms stating that if she does not pay R805 her account will he suspended. THIS IS COMPLETELY UNACCEPTABLE, FIRST OF ALL WHO THE HELL APPROVED THE SIM CARD WITHOUT THE APPROVAL OF THE ACCOUNT HOLDER, SECOND OF ALL MTN HAS DEDUCTED A HUGE AMOUNT OF MONEY OUT OF A PENSIONERS ACCOUNT WHO ONLY GETS A SASSA PENSION BECASUE OF AN ERROR THAT MTN MADE, THIRDLY WE HAVE NOW BEEN WAITING OVER A MONTH FOR MTNS ***** DEPARTMENT TO SORT THIS OUT. I AM LIVID AND I EXPECT FEEDBACK IMMEDIATELY!!!!!!!
