***** and bad service

I had a contract with MTN for a samsung tablet I took from them that I finished paying for earlier last year. I discovered in August 2015 that I was still getting debited a substantial amount of money even after settling this contract. I initially thought my partner was using a lot of a data on the tablet and ignored it. However, this continued a few more times and I decided to check this out at the Columbine square MTN branch where I was informed that another contract was opened on my name that I was not aware of. I was advised by the consultant there to call the call canter and request for this contract to be terminated. I did as advised and supp**** the relevant documentation but its February 2016 now and this matter has not been resolved and yet money is debited off my bank account every month since August 2015. I have been sent from pillar to post and nobody at MTN seems to know what their doing and its frustrating to say the least. I have now decided to block them from debiting money off my bank account because I cannot afford to be paying for something that I do not use and never app**** for. MTN really needs to get a wake up call and improve their service.
