Annoyed with Device failure!!!

<p>I have a Samsung Galaxy tab 3 lite that I upgraded my contract to a year ago. About a month ago my device refuse to switch on and I was advised to go into the nearest Vodacom store. The Campus square Vodacom store being the closest refered me to the Cresta Vodacom repair store. They intern refered me to the Eastgate Samsung store. The Samsung Store assisted me and advised that it was a software problem. I lost all valuable information saved on the device. Nevertheless I started a fresh. Today the device is doing the same thing again and refuse to switch on. This is not acceptable as I pay my installment on a monthly basis and need a device that works!!!</p>
