Services Activate without my permission

I called the call centre on the 06/09/2017 to load not activate a new decoder and I spoke to Thomas. Thomas decided to work out pro-rata and activated my services. At no Point did i tell that guy to activate my services. Now apparently I now owe multichoice r182.00 as services have been active since the 06/09/2017 till the 20/09/2017. I called the the call centre(not Sure) of the date and spoke to a Bohlale who reports to a Tebogo Khoza. I was promised a call retrieval until i had to call again. I call again on the 03/11/2017 and spoke to Tshepiso(who Reports to Ntando Thenjekwayo) ,mind you she was very nice and did her Job well. Ntando allegedly listened to the call and I was told that I need to pay since I said nothing when the Rep(Thomas) was calculating pro-rata. I'm forced to pay for service I never had because Thomas assumed that I wanted to activate services. I worked 13 Years for Dstv and I never gave such disgusting service.
