Mobilesplus and MTN money grabbers

After receiving my new phone and contract from Mobilesplus it was NOTHING what I asked for. Getting into contact with them was really difficult. I had to go to MTN stores to find out what to do with this unwanted package. I was send to MTN direct store where I handed in the phone and sim cards. I never used the phone but they are deducting money from my account every month for the past 3 to 4 months. When you phone MTN they say mobilesplus must cancel it and when you eventually get hold of mobileplus they say they are waiting for MTN to give them a number...for what??
