Cyberghost billing on Telkom account with no spend limit.

I received a notification a few days ago about a registration for something called CyberGhost which I did not subscribe to, I've never heard of it and have no clue what it's about, then I received my latest statement with a billing subscription added to it which I suspect is for this, today I received an SMS telling that I will be billed on my latest statement for June & July for activities which was not billed due to a system issue yet there should not be any activities on my telkom account. I don't even have a spend limit on my account so how is it possible that something like cyberghost could have been activated and billed on my account within my permission. I want this sorted out because I will take this to the ombudsman and the media. I am sick of continues problems with Telkom and their *********** staff.
