No Feedback-Poor Service-Pathetic Client Service

We started negotiating with MTN early in the year with regards to poor network service. We were ignored. We received an account for over R4000 for a ****le contract of R99. Our bank reversed the money and cancelled the debit order. We requested MTN's banking details and again received no reply for a long time. We then received notification that MTN had debited the ****le account with the amount 'owing' by us. MTN repeatedly asked us for the same details after we had rep**** to them in the same email thread with the answers. Still we received no positive feedback. Out of sheer desperation we eventually exercised our consumer rights and cancelled the two remaining contracts we had with them. We informed them of such. No feedback. We asked for cancellation fees. No feedback. We were given the excuse that there was a strike. But, our woes started before the strike and still continues after the strike. We informed MTN that we would no longer be using their services and that we would be removing our MTN sim cards. Still no feedback. Toady we received and sms informing us that we have to make a payment today because the account is overdue and critical. What a mess and disgrace!
