Address:

Sec 3 MIG 6 DEEN DAYAL UPADHYAY NAGAR, DEEN DAYAL UPADHYAY NAGAR

Have purchased Realme 108cm (43 inch) Full HD LED Smart Android TV on 1 july 2020.
I started facing a problem that is flickring of screen panel/Display of TV, screen is not working properly, picture is not clear, lining is coming in the screen.
As per the invoice and product page in FLIPKART it is mentioned that the TV is covered in warranty for 1 year domestic and 2 year for panel. and the warranty service type is On-site, BY authorised technician visit.
The Technician visited on 8th August 2021 and submitted his recommendation for replacement of the panel.
Till date (16 sept 2021) its been 2 months I havn't received any response from REALME. Whenever I called or wrote to them they simply responded back that they are working on it.
I really need help to sort out this issue.
