MTN Service an absolute Joke

I have been a loyal MTN customer for 20 years and have never defaulted on payments. In February I received an account for R3,700, 3 times more than my usual account. Trying to query this account has been a nightmare, I have tried to contact the service centre for 20 days to date due to the fact that the MTN stores are unable to assist with billing queries. I have mailed called and mailed some more, no answer !<br> I did however receive sms's to inform me that if I didn't pay the amount which I was trying to query my service would be cut, and so obviously I pay the amount in full. A week later I receive a mail to inform me that my account will be handed over after payment was made only because I was unable to query this account and yet I am still being threatened.<br> I am currently on the line waiting for MTN Head Office, my call was answered previously after being placed on hold for the operator for 6 minutes and then cut off by the operator. I think your service leaves a lot to desired and can't justify giving my business to a company who very easily takes but gives nothing back when service is needed. Absolutely disappointed in your lack of customer service.
