Xiaomi India — mi tv 4x (50 inch)

I bought mi tv 4x (50) on september 28 in mi store. That delivered on october 5. After than i requested for the tv installation through the mi store app. The technician came for the installation process on october 7. During the installation time we saw damages on the display (Between display and panel). The technician told they gave a complaint in the company. We are requested to repair the damage on the tv or replace that. But still now nobody won't give any response. We are very disappointed for buying this tv. Please give a response for your customer.
