Telkom changed my contract!

I signed a contract on 24 November 2014 for a Telkom Mix deal. The deal allowed me to make FREE calls from my cell to my landline and vice versa. According to Elaam, the sales consultant at the time, the deal included me being able to make free Telkom to Telkom landline calls. All of this was fine until I had to relocate. I arranged for the landline to be moved and the troubles started afterwards. Month after month I had to phone to have the charges credited for calls unfairly charged. Which they did initially. After calling again after months of not checking up on them, Lionel Steyn phoned me and explained that the landline number was not changed on the contract and that it was indeed Telkom's fault. BUT... he would also check into why I was being billed again for Telkom to Telkom calls. Since then, no word from the ***ard. Only feedback I have after following up on my own, is that the dispute was rejected. AND NO ONE CAN TELL ME WHY! He is the one who handled my dispute and now he's dodging my calls and refusing to react on the emails his colleagues are sending him about this dispute. I can't create a new dispute as a result. I'm being billed differently to my initial contract!!
