No response in SIX MONTHS of Queries

We have been experiencing billing issues from MTN since April 2015. I would also just like to mention that since then we have had NO feedback on this matter, besides auto generated replies. We are beyond frustrated, and have even gone so far as to lay a ***** claim as there is NO explanation for this confusion.<br> <br> Our account holds 3 x numbers and amount to R 1500 / month in payments. Since April this amount has varied from R 3500 - R 6500 per month! On numerous occasions, we have called the customer service centre, went into your shops and laid complaints via the website to get an explanation as to what these amounts were for but up until now, NO-ONE from MTN has returned our calls or e-mails. We were so frustrated that at the end of July I returned our debit order in the hope that this will draw your attention to this matter....however all I received was an sms stating that our account is overdue. So at the end of August, I again returned the ludicrous debit order of R 6500. Now, finally today MTN in all their wisdom has now suspended our account!!! Needless to say that not one of these queries have been responded to and we have still not had ANY feedback. <br> <br> <br>
