Unacceptable Service from Telkom

The service I had with telkom for the first few months of joining a contract with them is totally unacceptable.they been charging me an arm and a leg for their incompetence of not debiting when they should.to begin with I had to pay a penalty fee of R202 in November which they deducted on the 26th of November they only reconnected my line on the 9th December then my account was up to date now they insisting on adding another penalty fee of R202 for December which is unacceptable I refuse as I am not in arreas please explain.
