MTNs pathetic service.

I was contacted by one of their famous telesales consultants late July early August this year. My response was I don't deal with you people over the phone. Stupid me, I listened and was persuaded to take a contract. Weeks later the phone arrived, followed shortly by an invoice, pro-rata for September. I went to MTN Northgate for them to activate and make the phone work. I handed them my old phone and the new one. The assistant took out my sim and fitted it into the new phone. I questioned why I had received 2 new sim cards. I was told they are not necessary as my old card worked fine. To date i have phoned, emailed, and been into the branch as i dont get air time or data. Still using prepaid. Now I get told I have 2 contracts, one airtime and one data. The phone is not a dual sim type of device. If I need to make a call I must fit the one sim and when I need data I must fit the other. I had lodged a dispute within the first week. Spoken to countless assistants and no joy. The guy at Northgate now says we have to cancel the contract and do a new one. The next guy says I will be charged a cancelation fee. Doesn't look like anyone actually knows what to do. So after standing there yesterday for over 2 hours listening to music and the occasional, please hold, i am no closer to resolving the issue. MTN are pathetic.
