Philips India — tv replacement worst response

Address: No 21 ,Bharathiyar street,Srinivasa Nagar,Padi, 600050

I have purchased a philips tv in girias, mogappair west branch on july 15, 2016 which has a warranty of 5 years.in mid of feb 2018, tv was not working and we lodged a complaint regarding this. On 13/02/2018, one mr magesh from srinivas electronics,

Perambur diagnosed that the board inside the tv was not working and post then even the display was not working.
We again called mr. Magesh regarding this problem and he said that they are yet to receive the board. It has been more than 6-7 months still the issue is not resolved and when we call the service center we get a vague response stating that we have not received the board yet.
I have attached the necessary proof along with this. I need a concrete solution for this. I am expecting a reply at the earliest.
