MTN shocking and unreliable

MTN messed up my account and somehow neglected to deduct the right amounts from my bank account, putting my account in arrears. Then my service was suspended. And reconnected again after complaint here. The amount MTN claims to be in arrears suddenly changed from around R2,400 to R1,400. A week later my service was suspended again, ignoring the 14 days arrangement made. I called again, explaining what happened. I was reconnected and an arrangement noted that I will pay R1,400 by tomorrow. Service was just suspended again, now claiming I need to pay R2,695.<br> <br> I have made a complaint on here before. On that occasion I could not get through on 808 at all,but got an immediate response after posting here. I have now had to take time out of my work day again to sort out this mess caused my MTN. Currently holding and holding on to the clearly understaffed 808 line. And just cut off.<br> <br> I am very upset. What kind of service is this? As a small business owner I cannot trust MTN to bill me correctly or keep to arrangements we have made. I spend in excess of R12k per year with MTN and have been with MTN for more than 10 years.
