Contract Cancelation

I signed up for a contract with Telkom, via a sales person when a demo was being held at my complex, i called in to Telkom for assistance with setting the device up, the device could pick up no signal not 2g,3g or LTE.<br> <br> A Telkom representative at a branch recommended i cancel the contract as it will never connect in my area and said it would be beneficial to cancel it, i then filled out a cancellation at the bedford center branch but they refused to take the device, the lady said they do not accept the devices.<br> <br> that was in November / December, i have since been billed every month, spoken to numerous consultants and a team leader called Lungelo, the phone was hung up numerous times and i have not once been rude to any consultants, no one is willing to assist me with my problem, I'm just being billed every month for a service i am not receiving. <br> <br> i really want this canceled and my payments refunded as I am now TIRED of Telkom and the terrible service and just want to move forward.
