Been billed 3 month for adsl i am not using

Good Day <br> <br> I was first part of mweb I cancelled that account I moved to another. While working with mweb they transferred me back to Telkom ADSL to insure my wifi worked for the time being. This was only to last a month. # months down the line I am now with afrihost and I am still being billed by Telkom for the last three months for using the adsl which I never ask to continue. I have been trying for weeks now to get threw there call centre to get this fixed but all the phone does is ring. I want my money reimbursed to me and my data account stopped immediately. I just want the Telkom line so I can go on using my wifi. Telkoms customer service is non-existent last time I worked with the it took the 5 week just to fix my line. They never asked me if I wanted to continue there service or inquire if I have found an alternative they merely took my money and if you wish to rectify it they make it impossible to get in contact with them. In sort there aare probably one of the worst companies in the world. Hellopeter please help
