poor service

I was in a two months contract with Telkom which ended in March however they kept on deducting money on my account . i reversed all they none agreed payments. the line was blocked on the 17th , i called on the 18 th and only to find out that i was suppose to call in to cancel the contract yet we agreed on two years contract. i was charged penalty fees on top of that . i agreed to pay because either way i need to use the line . Payment has been made now i am told that i need to wait 7 working days to allocate the payment. i was on a call waiting for team leader for 30 minutes and the line was disconnected
