No response or delivery from MTN Canal Walk

A month ago my husband signed a new contract with a TV. We were told it would take 2 weeks to deliver the TV. It has been a month & still no TV. After 2 weeks the only way to follow up was to go to the shop directly which was out of our way but that's what we did as they weren't responding to mails which was being sent to them by the call centre reps. They told us they would follow up with the suppliers & get back to us. The only correspondence we received from them was when WE called THEM. We, as the customer don't want to hear about the suppliers issues, those issues need to be sorted out between MTN & their suppliers. We don't receive any apologies just excuses. My husband is on the verge of cancelling the contract as the phone we received hasn't been used & MTN hasn't delivered.
