Debited for ********** calls, even after reporting

MTN decided (on their own) to open our business cell number for international calls. Suspiciously, we then had a HUGE bill (over R10 000) for international calls run up on our unused dual SIM.<br> We disputed to the legal dept over a month ago, asking that they investigate internally - with no feedback. Meanwhile. we cannot use the phone half the time, because of 'no airtime'. And MTN took the full debit order from us, AFTER we had a case number from legal department and we had asked that they not take the full amount until it is resolved. We corrected it with our bank, but now MTN has taken the full amount again. And we STILL cannot make outgoing calls on our phone!!!<br> And no-one comes back to us. MTN doesn't seem interested in resolving the situation. Very unhappy customer....<br> <br> Apparently, our credit controller is Michelle Bawa, but you cannot get hold of her on the phone and she doesn't answer emails. Very frustrated and angry at the lack of service, communication and problem resolution from MTN.
