Rework for the third time!

Screen needed repairs, my insurance company allowed me to choose a place to get it fixed- biggest mistake ever!<br> Not even a month later the screen showed an lcd fault, assessed by another company as well I go back to the store- greeted by rude staff, they walk to the back have an obvious laugh that I expect them to replace the screen at their cost and the techinician walks back saying its water damage and they can't be held responsible- this without even opening the phone! Not to mention I also had an issue accessing my applications that required data, and could not connect to my service provider or any wifi to resolve this,for that the rude techinician says I need to update my iOS because they connected to the store wifi and everything was good, which was total ******* as my sister picked up it was my VPN causing connectivity issues. After much frustration the manager replaced the screen still insisting its water damage from normal atmospheric moisture?!?!? My water damage indicators were not even red, but according to the technicians it had speckles of pink on It?! Clearly not an original screen. Now my screen has a fault for the third time & I'm running out of space :(
