CONTRACT UPGRADE BUT NO PHONE DELIVERED

Call Centre from Cape Town phoned to advise that my existing contract was due to expire and I could upgrade telephonically with them. After a lengthy conversation they confirmed that I could upgrade to a Samsung S6 handset. This handset was to be delivered to me. After waiting a month and not receiving anything I phoned the Head Office and was told that the phone had been returned because the courier company couldn't get hold of me. It turns out the number they were trying to contact me on was a cancelled contract which had expired 2 years ago!!! The lady I spoke to then apologised for the incorrect cell number being given to the courier company and promised that the handset would be couriered again. It's been over a month since that phone call and still I have no phone... :(
