Vu Televisions — Very very worst Tv service also customer service

I was very happy when I bought my first led vu tv in 2019.
But after getting lot of frustration I'm writing this.
Since July 2021 my vu tv back light has been changed three times. But still now my issue has not been resolved by your respected dealer M/s cemos computers Trichy.
I think service technicians are not upto the mark.
They are not using company materials for servicing.
Very poor response and customer service.
If this situation continue then your brand will be in a bad state.
