Bad service and customers ****med

Now these people are ****ming elderly people. My mother inlaw has been a loyal customer for more than 15 years but DSTV prey on her because they losing subscribers because of their arrogance. An agent called and told my mother inlaw that she was selected and family would receive R23000 cash or paid subscription for 3 year when she passes away and she was pleased. The agent continued and oofered her funeral insurances for R69 a month and she said she wants to think and they should call her tomorrow. She waited for the call and he never called and I went on her app to check if all is in order but to our surprise there were amounts added and decode insurance added without her approval and knowledge. She went to online chat and the agent promised to escalate the matter and it will be fixed within 48 hours but it's been 4 days now and her account still on R748. How could a pensioner afford to pay this amount and for something she doesn't know. DSTV is cruel now and taking advantage. When they call and offer your free things don't accept anything cause you'll be billed *****ulently. She's being ****med now
