Don't take any contract with MTN

I upgraded a contract in June when one of their VIP representative Vicky Roux called. Little did I know this was the beginning of a nightmare. Firstly the device was delivered late. Then when it was delivered it was not working. I took it back to a MTN store. They took back the device told me to call in and since then I have been calling daily the whole month of July no help at all. I was basically told by their customer care that there is nothing they can do but I must just suck it up and pay for the device i don't have and to do it instore next time. Calling Vicky or emailing her is also useless she just hangs up the call and does not answer the email
