MTN Unable to Resolve Problems

I was recently persuaded to upgrade to a new contract. Following my upgrade I have been completely unable to get any data services, although my contract includes data. I have visited the MTN Store at Cresta Centre, Johannesburg, who after over an hour were unable to resolve the problem. I have telephoned the MTN Customer Care line, only to get a long list of menu options none of which enabled me to speak to a consultant or to get any closer to resolving the problem. I have contacted the MTN Customer Care e-mail address, who asked for a whole list of personal information to confirm my identification, but then referred me to the MTN SME Customer Care e-mail address. Again I was asked to provide a list of personal information to confirm my identification. Two days late I am still waiting for any response. For a communications company this is pathetic.
