No response from Telkom re hello peter complaint

This is my third post re the same complaint. Telkom phones me they promise to look into the matter then nothing. It seems I may have to go to the Consumer Commission. The contract agreed was for per month and theyve sent me the wrong phone at at 350 per month. In the meantime I have to use the phone because I need it for work. If telkom can make it worth my while I why I should accept expensive phone when I didn't agree we can overlook matter . I hope they will resolve the matter and not just make an empty promise
