HIGHLY IRATE/FUMING CUSTOMER

It is with utmost disgust that I have to report this problem on Hello Peter, because the consultant so ever kindly put down the phone on us. We were not even given a name, she could in fact make a lemon cry. The disinterest in our very important problem was clearly nothing to her. After spending 30 minutes of holding the line for this *********** consultant, we still sit with the same problem. Why are these people hired if they can't do a simple job of being respectful to their clients. Now for the real problem, we do not read through bank statements daily as we have busy lives. Apparently, we owe MTN over R1500, however, after taking a look through our statements, MTN has not even tried to debit the money. So what actually is going on? We have had service this whole time, up til now, so nobody knew that these debits were not going off. Now we are expected to pay an outstanding balance, not because of our fault, but because of MTN. I will not pay this amount, I will rather cancel this contract than have to deal with fools called consultants again. Why has MTN not been deducting the amount on the debit order date? It is not my problem, please fix this asap! Thanks
