Unauthorised Termination

I have been billed R653 in December and R1215 in January for a contract that's R569pm , when queried on the 28/O1/16 I was told it was due to termination fees something that I have NOT authorised and that feedback will be given in 72 hours called again and told it is 72 working hours , called again 2 weeks later was told case has been assigned and will be contacted , it's been almost a month and I am yet to receive any feedback , I have been calling the call centre continuously and with no joy , I called today and was told that I was called on the 13/02/16 , when I asked what number was called, I was quoted a number I have never heard of before , furthermore I was very rudely told by Sinithemba that he is back office and cannot do anything, before I could ask him to correct my number and log my query correctly he abruptly put the phone down on me , Telkom was very quick to call me to enter into a contract and take my money but very slow in returning what you have wrongfully taken
