Telkom system charging without approval? Have various reference numbers

Bad Bad bad I am just being charged and I have various queries and still not fixed. I moved a telephone line from one room to another was told it will be R450 once off I said go ahead, Telkom are charging me monthly I have told them that this should have been a once off thing, was told I was correct and system making it monthly which is now at R608 which is much more than my line rental of R209 this has been going on for a year??? in addition without me requiring it I am now being charged Closer 100 bolt on at R70 I have never requested this and not again the system automatically charging this is unacceptable
