*****ing money on products I don't use.

I have enquired about a contract and had given my details for credit vetting without approval. I received a SMS telling me that an agent will call me soon but instead they had sent me the product via courier without my approval and concent. I called in on the same day as delivery to cancel my contract which they had processed. When j called in on the seventh day again to verify my cancelation as I have a seven day cancelation period they could not find any cancelation request so j cancelled again. I called them again after a week and I was told that I have to pay a percentage of my contract total of two years to cancel because it had been after the 7 day period. I told them I called twice to cancel within the 7 day period and the assistant said she will follow up. I now receive statements of my contract which I still had not opened and which is still not cancelled. I have tried everything to cancel with no response and I am charged for something I did not want or agree on. Telkom has the worst service and will never improve. They do not care about cancellations and only want to ***** customers money.its not the first time I'm trying to cancel something with them. I have tried canceling a landline and ADSL line for the passed 5 years which I don't even have but I am still charged for it for the passed 5 years. I have had enough of paying for things I don't use and they can't seem to cancel.
