LG Nexus 5X sent for repair. The phone was broken ...

LG Nexus 5X sent for repair. The phone was broken by negligence of my client and is therefore not under warranty (it's true the USB C port was damaged). Quote very expensive.
The problem is that I asked for the return of the unrepaired phone to do the repair myself since the warranty was dead. What a surprise to see the tablecloth of the net cut battery and a pad of an antenna connector to the plastic back shell ripped off! Thank you MobileTouch AG for your "professionalism". I'm afraid to send my own phone to your home as a guarantee now.
To avoid if possible.
