SONY XPERIA Z3

Screen is pulling loose from phone and does not want to switch on.<br> Phone not even 6 months old.<br> Repairs says: Screen is loose, phone bent and water damage.<br> Not willing to fix the phone.<br> <br> The phone is advertised as water proof? - how can we have water damage - was not even close to water<br> How does the screen pull loose out of the casing?<br> How is it possible to bend a phone?<br> <br> Nokia Lumnia still working strong after years.<br> <br> Really not happy
