Telkom is *******ly billing for a service they cancelled

During March I requested a service re-location to be done on the 29th of that month. Instead they suspended my service on the 15th of March leaving me with no service but kept on billing me. I moved to a new address and after weeks of trying to get a ADSL line they eventually installed a line with a new number - note I was getting billed for it. Every single agent I phoned during that period gave me different info and each and every one said the are "escalating" my case. In the meantime I am getting billed for BOTH lines - even the one THEY suspended ??? And now they added a weekender option to my new line which I DID NOT REQUEST as I do not make any calls - this it is just for internet. I am so fed up and now the agents are telling me that I should pay the arrears for the number I DO NOT HAVE and now apparently still shows active although there is no usage or risk getting my service at the new premises suspended and blacklisted????? I will never ever see a refund on my account if I pay them as I do not get ant feedback on online disputes either. What now?
