Staff not keeping promises

I visited the MTN Tygervalley branch on Tuesday 20 October 2015 to cancel an upgrade (the contract is on my mom's name but she took a phone that I didn't want). I spoke to Adam who logged the request for the cancellation of the upgrade. He said it would take 2 - 48 hours to receive feedback which he will then convey to me. He also gave me his cell number in case I need to call him. On Thursday I tried calling a few times but never got through. I sent him SMSs but he hasn't responded, left voice messages but still no feedback was received. It's been 5 days now and I still haven't received any feedback. <br> <br> Seeing that my original contract is close to ending, I am rather going to move my contract over to a competitor who I know will give me better service as I have been dealing with them for the past few years on another contract, and I've never had issues. <br> <br> Also I'd like to comment on your store layout. I think the layout you have in all your stores is not working and is causing a lot of problems because customers are always complaining every single time I have to go in to an MTN branch. Sort yourselves out before your business goes down.
