I bought device from flipkart and its fell down after few days and Brocken front glass . then contacted google for changing glass, as per their instructions i hand over to their courier team then to google service provider b2x. After few days i received quotation from b2x claiming 24000 frs service cost for a phone it self cost 30000. and they mentioned many damages which wasn't there when i hand over my phone especially they are saying device doesn't turn on but it was working fine when i gave my phone i have proof for that, i took images of my phone when kits Brocken the device was turned on and working. what if something happened while transit my phone or while repairing whos responsible me or google i contacted them response was not at all okay, it s been 2 months almost i am following with google .
