Pathetic service

In July I did an upgrade on my contract, got a faulty phone and took it back. They sent it off for a warranty assessment and got confirmation that the device should be replaced. At the time, they did not have stock and probably still not. The manager Louise said they don't know when they'll have stock. That's when decided to purchase a new phone and cancel the upgrade. Not one of those *********** sales personel can cancel it. I'm still paying for something which I don't have. They don't give you any feedback, you always have to call them to follow up. Ayanda's attitude stinks and he refuses to assist me even though he booked it for the warranty assessment. Brian who originally did the sale, now wants nothing to do with the case. Rory, who's handling the case now, only follows up with their retention dept once I come into the store. Customer care, useless, every time I call, they can't assist me. This has been coming on for almost 2months and should have been resolved by now.
