Again Disgusted and Totally Gutted

So following up on my previous complaint dated 06.03.2015, Vodacom came back again stating that its liquid damage to my HTC, same as what they told me a few weeks ago. Sending me a picture of the damage and have the audacity to quote me R7 399.00 + VAT for a new device. Yet the more i tell them it is at no fault of mine and manufacturing issue, they are adamant that to them its liquid damage, nothing i can do, whether its at my fault or not. So to me it seems like they want to take the easy way out. Although they a service provider, to me they DO NOT have any measure to retain their customers, in fact to me they take advantage of the fact that they the \best"service provider ito their network coverage"
