Miss leading sales and no delivery

On Friday 21-08-2015 I was contacted by the MTN call centre regarding an upgrade offer on my contract. The sales agent claimed to be offering the best deal available and only available for that day, a deal not available at any of the outlets. However we did find a better deal in the MTN brochure. The real problem though is that the cellular phone has not been delivered and more than two weeks have passed, the courier service claims they were unable to find the residence and the device was returned to MTN. I spoke to Cindy from MTN on 03-09-2015 to cancel the upgrade, she gave me a reference CIN0309. The cancellation had not been processed and this is unacceptable.<br> Yesterday I called in again and spoke to Thandi who told me that there is no record of the cancellation request and said that they will request redelivery, reference UV752743. I am not happy with redelivery, who knows how much longer I will have to wait for the device to arrive if it arrives. Firstly I would prefer the cancellation so I could go to re-apply and take a device from the store, secondly what compensation will I receive for my time and inconvenience caused as well as costs incurred by the calls I made.
