Huawei — nexus 6p - no service issue

Website:

I'm a very dissatisfied and frustrated owner of a google nexus 6p device. This device has only been giving me trouble. From september 2016 the gps navigation on this device stopped working for some reason. Now, on 29/06/2017, the radio has stopped working and the device says "no service" for any sim card. I have called nexus support, who have been not helpful at all and have been very very arrogant in their tone. I have taken my phone to huawei service center and was told that this problem is being faced by many nexus 6p users after the nougat update and we recommend you to downgrade the firmware yourself. The only other option is to replace the motherboard of the device! This is not at all acceptable! The device is in pristine condition and never ever been dropped or misued or mishandled. I demand google to look into this issue immediately and solve the problem which thousands of its users are facing worldwide! Please check your product forums with thousands o[censored]sers reporting the same problem. We need an answer google!
