Xiaomi India — Mi redmi prime 2 16gb white

Address:

Ahmedabad, Gujarat, 380008

Here, I have a problem with the application named as XENDER.
the application doesn't allow us to create or join the group. In other xiaomi phones the process is proper. I had also updated the software from company authorized service center. They can't understand the problem. I had a many times complain to xiaomi customer service for technical support for my mobile phone. I have been fed up with the same problem. Complaining about the same matter again and again. There is no response.

If not I want the replacement for my mobile phone.

I think my problem will be solved soon
Thank you
