Edcon dishonest to its customers

Hi everyone, I went to pay my account, as usually at Edgars on Saturday,but I have been wondering why do I have to pay so much money hence I don't utilise this account, but every month I pay R400 plus, when I checked with the service centre at Edgars, I found that they re-activated the family provider plan without my concern, I cancelled this plan in December 2017, and there are things that I was charged for without my acknowledgement, sms and control chat and airtime that I wasn't receiving, I got a call from someone claiming was working for Edgars doing promotion about data but I suspect they make us join things thinking is promotions, when we calculated with one of their employer,we found that I was supposed to pay less than R200 since last year I guess, these things when we calculated them for this month were R235 imagine how much since last they ****** me.
