Onida / Mirc Electronics — onida led smart tv remote problem

I bought led smart tv through flipkart in sep 2017.. There are frequent problems with remote. I registered complaint and it took them almost 3 months to replace and th replaced remote also had problem after working for just 1 month and agin raised complaint and it is already 2 months over still the remote is not replaced.
The technician visited both thw times and said battery issue and goes off saying the part is not available..
I called up the customer service but they never listens inturn give aervice center number.
I am unable to use smart features and is justusing as tv after spending so much of amount
