DSTV Biledl me for free SHOWMAX TRIAL (****************)

South Africans, please listen to this. I received an email from SHOWMAX to run a 14days trial at no cost. I even made a note to cancel on 12th day. To my surprise I got billed by DSTV MULTICHOICE and when I call to check no one at DSTV can tell me what the issue is. SHOWMAX checked and said there's no account that is outstanding under my profile. DSTV has loaded another bill waiting for me sometime before month end. I had a chat with 2x operators and they both cannot assist me. Now the big question is what should I do in order to get my R99 back and remove the idling R99. I ask DSTV to resolve this matter before I make noise about it please.
