Consultants making a pensioner add extras to subscription

DStv consultants calls the elderly and makes them sign up for all ****ty things. My mom a 68 years old, ended up signing up, the details on the policy is not even a name one would have. From paying R129 now she has to pay over R500. we have called and asked for these to be cancelled since last month but nothing has been done still. this is so unfair because how can a pensioner afford to pay over 500 for a 129 subscription. stop fooling our parents and cancel those added things because she will not pay. we have asked an explanation of the balance brought forward that she now suddenly has and still no one can explain. if you want us to cancel the entire ting, let us know and we will do so
