Xiaomi India — Xiaomi MI 5 stuck at MI logo after V8.0 update

Address:

I am an user of Xiaomi MI 5. I have been receiving Xiaomi v8.0 update notification for 2-3 months but I was avoiding to update the same. Recently I agreed for update and after update the device doesn't boot, it's stuck in MI logo.
Now after visiting service center and talking customer care I get only one solution complete format of device and LOSING all DATA.
It makes me wonder how a company for it's flagship product provide such an irresponsible solution to fix their BUGGY SOFTWARE UPDATE.
First of all their Buggy Software Update caused all the harassment and on top of that they had HACKY solution.
To worsen the matter their customer care and service center BLUNTLY REFUSE to register a complaint regarding the same. They said that the solution of formatting the phone is fine.
I request for further escalation of the issue to the right team to address the problem but it seems they are simply ignorant to PHONE problems and customer grievances.
I would like to know options and path to put and take forward the issue.
Thanks,
SP
