Big Bazaar / Futurebazaar / Future Retail / Hometown — Service complaint

I purchased a koryo led from ezone gip and installed it my village. I also purchased 2years extended warranty.

In the month of dec 21 there was a problem in my tv so I registered a complaint on 20 dec 21 ew Complaint number 279946.
Koryo complaint numbers [protected]KRLE0002

I-got 2-3 calls till now from service centre or customer care the are asking visit done or not even after that not a single engineer called for the complaint.

I aggressively need a solution. This is not a joke you are not giving proper services to customers. It’s already 6 months done.
