Dstv ***** and no assistance

On 23/04 I recieved a sms from dstv confirming my account has been activated and a debit order will go off. I called dstv spoke to Nompilo Zulu, explained to her that I have not called to activate dstv as I have not owned a decoder and cancelled my dstv 2 or 3 years ago. She assured me that it will be cancelled however on 03/05 I was debited again. Called dstv spoke to Cade explained that I have not authorised any debit orders and that this is ***** as who is using my dstv account and my banking details, she said no one called to activate my dstv account the system did it. Asked to speak to a manager who was supposed to contact me and yet no one has. She said she was going to escalate the matter and have it cancelled and yet I was debited again on 27/05 for double the amount. This is ***** that dstv is debiting my account against my authorisation I don't own a decoder and don't wish to have dstv. Please can someone contact me and officially cancel my account on your system. If this is not done an official complaint will be logged against dstv at the police station.
