BAD BAD SERVICE. FIX UR BILLING SYSTEMS!!

I recently received an invoice from Telkom billing me R300 for a whosale line which im told is a migration fee for an ADSL line that was NEVER with Telkom.Telkom installed my phone line and immediately after the order was closed my ISP submitted a new convert. I logged a billing dispute and i was called back and told to query the charges with my ISP. How one earth can i query charges on a Telkom invoice from a different ISP?????. Im being told on the one hand by your advisers that my line was never with you guys and there is no reason why my dispute wont be approved, then on the other hand im being called and told the charges are valid and that i should query it with my ISP. I want to know what this R300 charge is for and i want TELKOM to answer that question. I refuse to pay for a migration fee when i never migrated my line from you, because MY ADSL LINE WAS NEVER WITH YOU!!!!! My line number is ***. Reference for the dispute is ***1.. I expect to here from you guys soon. I want this sorted. Treat people with some compassion and respect or deal with the consequences. Telkom if u dont sort this out i will be in contact with my Legalwise i have been dying to use it!!
