Telkom has turned into a ****

I have a contract with Telkom which was due for renewal in May. I went to the the store to ask for cancelation on my contract end date, or give notice for cancelation but was told i have to wait for the expiry date before i can do that. When i went i was told i was supposed to give notice. I am now stuck with them for another month and on top of that they keep requesting payments on the wrong date and if it returns unpaid they charge me rejection fees. Been struggling with them since February, none of their stuff seem to be skilled enough to resolve billing issues.

I have been paying R269 for almost 2 years, now that my contract is due for cancelation they are suddenly debiting crazy amounts.

My account status always says in arrears but they get money from me every month.
