Deducting a money and nr is with different SP

I have taken over a contract from my mother when I started working. It was a contract on my name and ID nr for about 2 years. I have cancelled the contract with SP and then moved to telkom mobile where I had a contract since aug 2014 with the same nr.<br> They started deducting money from my mothers account in September 2014 again after it has been on my name for 2 years. <br> The problem is still persisting and now they are claiming that I need to keep on paying for BIS as I never cancelled the BIS. After many hours on the phone and showing on the system that the phone nr has been taken to prepaid in July 2014. They still have this excuses and *********** service consultants. <br> They only want to refund a third of the money they have wrongfully deducted from my mothers account. <br> I feel that this is ***** and theft. Each time you speak to a different consultant, and get the same response, 21 working days then the problem will be sorted, and still nothing has happen since we have started with the complained in January 2015
