Incorrect billing

WHAT A ****TY & DISAPPOINTING SERVICE.

DSTV is ripping customer's off. I have been billed for DSTV Premium which was upgraded without my knowledge. The live chat agent told my that the premium was ordered by me online and I can assure you that I did not order any Premium. The agent further advised that if I want to cancel this premium I need to schedule for cancellation which will only take effect on your invoice date which is on the 1st of each month , this will impact my compact package as the account is now overdue with R699 , and my services will be disconnected should I not pay the full amount. This is totally unacceptable DSTV!! I did not fxcken order Premium streaming. I am checking under "My Product" and it shows that my Premium is inactive, so how the hell do I owe Premium?? Please sort this out ASAP or else I'm cancelling my contract, this is unbelievable, what a *******!!!
