Hi mi india team. I have purchased a new mi tv 4x 50cm at mi home coimbatore on 21.12.2019 vide sales order no: sa[protected] and tv serial# no: 22154/[protected]. From the day1 of the installation tv picture is shaking intermittently which leads head ache.
To the viewers. I raised a complaint on 24.12.2019 vide ticket no: r296559. One service engineer came and just informed that mi 4x tv models are having common problem of shaking picture when they are normal channels and adviced to change all hd channels.
How could it possible to have 1000s of channels in hd quality? The similar model in nearby house is working fine. I already requested to replace the faulty tv but the service engineer came was having less knowledge.
Instead of analysing problem he tried to convinence us to change all hd channels. It is regret to say that being a world wide branded mi having such very poor service engineers placed at coimbatore.
Today also i raised a complaint again to replace the unit after due analyse by a qualify engineer. Complaint no: r307991 date[protected]. Pls take a necessary steps to address the video/picture shaking issue or replace it by a new unit.
Also pls share me the next high level contact details to escalate further. Thanks in advance. Am happy to share further more details should you require
