Xiaomi India — volume button not working

Address:

Proddatur, YSR, Andhra Pradesh

Dear sir/madam

I mr. Ravi mekala and i purchased redmi note 5 pro mobile from flipkart through online dated[protected] from the second week of purchase, the volume button does not work suddenly it's stopped. And i searched and learned via youtube video for the solution of the problem and i have done my mobile reboot then it works as usual but after doing it works only for a while and does not work the volume button again. So i've visited to the mi customer care in proddatur and i explained the problem briefly to the people. And they taken my mobile keep in their service point for an hour after they returned and said that your mobile repair is over. Then i left from them but the trouble came just 6 hours after the repair was over. And the customer care person says if this problem persists you should change your mobile software...! I do not understand!!! Why should the software change to this small problem? And it's deeply hurting and very sad for me. Please solve my problem.

-please do the needful

M. Ravi
