Disgusting Telkom service

I took a new contract with Telkom in May 2018, the device was faulty from the inception of the contract. Within the 4 days I took the device in store for assessment. At the Chatsworth Telkom store I was told that there is no fault with the device and the consultants refused to assist, on my insistence that the device was faulty as it was getting hot and the battery dying, the device was booked in. I waited 2 months for a replacement or repaired device however was given the run around by Telkom staff. Eventually Telkom agreed to cancel the contract. 6 months later I am still being billed for the contract and added charges yet I don't have the device nor Sim card. I have appalled by this behavior from such a huge and prominent business. The service I received from the store was disgusting the Telkom staff did not even bother to communicate with me regarding the contract but are fast to debit my account. Pathetic service
