Cell Cee no service.

I was offered an upgrade 2 months before my contract expired. With clear instruction on the type of phone i wanted and not to change my nr (all recorded), i got he opposite and a 2nd nr after all these years. I cancelled the 'upgrade' and my contract and took one from Telkom (great service). I paid the contract termination fee in at Nedbank as requested. Monies was still deducted for 2 months afterwards and i can't reverse them. After numerous visits to different Cell C shops, i was promised feedback, but in vain after 4 months. Why should they worry, if you can ***** money from a client and you can get away with it, why not do it to millions of others while most other people will simply just give up, because it is in the order of the day in this country. If they can't give service - then why support them?
