Huawei — nexus 6p - crashes after ota update

Address:

Gurgaon, Haryana

Huawei Reference: 38403231
I purchased the Huawei Nexus 6P 64GB on 9-April 2016.
There was an OTA update on 13th/14th July 2017. After this OTA update, my phone worked fine for a few hours. Then it automatically rebooted and since then it is stuck at the startup Google Logo, and is constantly restarting.

I called up the Huawei Customer Care on [protected]. I was told that there is no solution to this problem, and the only way to fix this is to get the motherboard replaced. The cost of this would be INR 20k approx, and can be done at the authorized service center.

I called up the Delhi and Gurgaon service centers. Both service centers confirmed the same. They also confirmed that this issue is not an isolated one. A lot o[censored]sers have faced this issue.

I cannot accept this resolution, and want to escalate this concern to higher authorities.
If I have installed an OTA update, which is an official update provided by the manufacturers, and because of this update if my phone is bricked / crashed / rendered useless, why am I penalized to get it repaired?
This is clearly a case of negligence from Huawei, and I cannot accept it.
