Volume key broken and not working.

Hi. I am using redmi note 3 and it accidentally fell down from my bed today and it has got a dent towards the volume down section of the volume button. The volume button wont work and neither is the power button working. Whenever i press the volume up button the volume reduces to the lowest and the power button just doesnt respond.. Please help.

It would be of great help if you can tell whether or not it is repairable.. If yes then please tell me how. It has only been a month since i got this phone
