Ripoff for cancelled lines

On 7 Oct 2015, I cancelled several telephone lines. Telkom continued to charge me and even suspended the ones I needed, I paid reconnection fees for cancelled lines. When I wrote to this forum, they found a credit of about R2000 whereas they were collecting about R1500 monthly for rentals. About two weeks ago, I lodged a dispute for this **************** at their Hemingways Mall shop. I am still sitting without a line in my small business. They cannot transfer the line because I owe about R6000 for cancelled lines. S. George is the person responsible to deal with the first part of my problem never gets me on the phone and simply writes that on their system and continues sitting, waiting for me to know what is on their system. Had I not sent him an email, he would still be waiting to locate me on their internal systems. It's not clear why I deserve to sit with no phone for three months because of their effeciency.
