Outsurance and TT3 digital group horrible service

Am very disappointed by the way outsurance handled my situation. All insurance do thorough investigation when they will have to lose but if its gonna be beneficially to the client, the client can go jump. My child's tablets was repaired by TT3 group digital in December 2017 it has cracked screen. Ever since it came from them it malfunctioned but since my son have ipad also which is insured in outsurance, i only picked up mulfunction late. And am not happy that now their diagnosis is that the tablet was immersed in water but the tablet is operational but freezes and goes to safe mode and we can't take it out of safe mode. It was gonna be fair if the initials diagnosis in December was water damage but now when i know for certain that there was no water damage, i can't accept that TT3 diagnosis. As a matter of fact am stopping insuring my devices with u what is the use cos now am sitting with non function device just because i must accept TT3 diagnosis.
