Shocking service, zero assistance

Two days ago i noticed the screen on my iphone 5s was lifting from the phone itself. It had not been dropped! I took it in to the Pavillion this morning as it was the first chance i had, only to be told (and laughed about!) that the warranty expired yesterday.(12/2/). I was advised they could book it in for repair at my cost but that would take two weeks, I should rather take contact my insurance company. I have had a contract for this number with MTN uninterrupted for approx 8/9 years and that is the great service I can expect. Seriously irritated, Shocking service. When this contract is up, I will most definitely be moving to another provider.Istore advised its due to a technical issue with the battery, MTN no idea, clueless, just laugh and find it amusing. One day for a phone of that value and after 9 years of service, pathetic!!
