bulled from pillar to post and no results

Furious at your call centre telling me I will b billed for a device that was handed in to Telkom CW. It have given me problems since the 1st two weeks of having the Wi Fi Router the cancellation department gave me a call and I spoke to Neo and she gave me a whole lot of BULL that I should fetch the device from the store, still I will b billed for a device I have to pay R2,568 if I cancel. Then I spoke to her Manager Thulani,who have no interest in my issue and I explained to him the whole story and yet he said I should fetch the device and see in a month how it work! At this point I wan furious and ashed if he just woke up from a sleep and he sounded Very tired and not helpful at all I need to know asap what's gonna happen next I DON'T WANT to use Telkom as u still have 2 cell fones on contract with them
