Xiaomi India — Board problem in my redmi note 3

Address:

Chennai, Tamil Nadu, 600047

Hello guys.. I have given my redmi note 3 in mi exclusive service center on 21/05/2016 which is located at velachery. They promised that they would return it within a week or so. But then i went there and asked them if it was ready. But there anser was no. And still i didnt get my phone. They always told me that they didnt get the parts. And its been nearly a month. I request the company to take severe action on this issue. And this is true that this will be the last and final product which i will use in my life.
