MTN getting more pathetic by the day

I send MTN E-mails to both their customer care & credit control departments, as trying to get through to their \call centre"is a nightmare. If you can get through in less then 7 minutes you are very lucky. My line is currently suspended even though i always pay the amounts outstanding as per my billing invoice or the reminder SMS's MTN send me. No one ever got back to me even though I received auto responses with turn around times. Can't wait to leave this network after over 7 years of giving them business"
