not bringing their side of the contract

So I have called telkom went in to telkom store and reported on hello peter that the are billing me for a contract that I did not sigh for. Still nothing is done. So I can not do more than this and Telkom does not want to fix the problem. Please cancel my contract and refund me my money as you are not abiding your side of the contract. It has been 5 months and still nothing. WORST service of my life. I really have tried but it is impossible to talk to you and to ask for assistance to fix what you have did wrong.
