Xiaomi India — Defected piece replacement taking more than a month

Address:

411018

I bought a redmi note 3 and i got defective charger.
I made a request through service center. As of now i haven't got my replacement and it's been a month since registered request.
Also service center is not receiving any calls.
Xiaomi has very bad after sales service.
If anyone got defective piece then try to replace or return asap if possible. Don't go for repair.
