Xiaomi India — mi tv received as broken and no response from support

Address:

560100

I have receive my tv screen broken. I raised the complaint woin[protected]. I didn't receive any call /sms/email from them. When i contact customer support they don't have any answer regarding the status. The only answer i got is "please be patience". Every day they are telling backend team will call me in 24 hours. But they never called me to update the status.
I don't have option also to track the status. There is no escalation matrix for mi.
