razer hammerhead true wirless not working at all

I don't even know what to say it was my first experience buying razer stuff and it was so bad yesterday it arrived and I tried charging and pairing but didn't work I tried looking into instructions once again didn't work tried googling also didn't work when I finally decided to contact support I asked if she speaks English and she ended the chat today I decided to write again but when I entered my serial number it said I don't have a razer care or something also if you didn't understand the problem the earbuds not working I guess case is working but not earbuds cause case shows green and earbuds not doing anything I tried resetting it by tapping I thought it might be the problem of my phone I tried to to it to PC and my friends phones didn't work either other audio device connects
