MTN strikes again!

I was forced to cancel my contract on Friday due to the incorrect contract being given to me in the first place, as admitted by MTN. I had to pay for this cancellation before any of the 6-call center and 1 instore agent would attempt to offer their horrible excuse for service. I thought all was okay when I was finally able to load airtime onto, what I believed to be my now pay as you go sim card, via my bank account, but no airtime loaded. The money however is out of my bank account. The beauty is I get an SMS on Monday to say my contract will be cancelled in September and normal contract payments will apply until then. This contract is a data only package with no option to add airtime or data. There is no way on earth I would have agreed to this. I use my phone in my business. I have requested the recorded call, but that request has been ignored. I have been told that I am not allowed to know the supervisor's name of the person that made this contract mistake. The cherry on the cake is the phone call I got from MTN a few minutes ago to ask me if I want an upgrade because I am a valued client. If that is how you treat your valued clients, I can only imagine how you would treat everybody else!
