Charged for services I didnt sign up for

I am absolutely disgusted with the poor service from Telkom. I was signed up for a landline-lookalike service that I didnt sign up for. I had asked for this to be put on hold until I had clarity on whether Telkom could port my Neotel number to Telkom. When I queried this I was told that Telkom would be able to port my Neotel and that I must not return the device. After over 6 months several emails and calls Telkom was still not able to port my Neotel numebr to Telkom. I had asked on several occasions that this service be cancelled and the device be collected. I am now being harrassed by Telkom and their debt collectors for a service that I never signed up for or used. I have all the hellopeter complaints and emails showing all of the above communication was made. In addition, I have 2 other contracts with Telkom, and pay in excess of this amount on a monthly basis without having defaulted on any of the payments. I need someone to contact me urgently and sort this out as I have now been handed over to debt collectors due to Telkom not doing their jobs properly.
