Billing when not auhorised and not cancelling after several emails and calls

Trudon has been charging my telkom account for the past 2 months now. I have told them that there has been absolutely no authorisation by myself. This is being charged to my TELKOM account every month without my permission. I contacted Telkom who passed the buck and said I must contact Trudon. Several phone calls and emails and 2 months later and I still have no reprieve and still have over R1000 billed to my Telkom account every month. Trudon have not rep**** to my emails and this is becoming a nightmare to deal with and I believe they deliberately make it impossible to get any solution to the problem. I believe I am by far not the only one with this problem as I have seen several comments and complaints about the exact same problem online.

I demand a full refund of the past 2 months and the contract to be removed off my telephone bill immediately as I am not going to pay these bills.

Ref on my telkom bill as per my emails which I sent are: Ref: ********** 251 Ref: ********** 451
