Vu Televisions — TV not working in 25 days of purchase of 3 year warranty

I had purchased tv from VU 55" television on 27 June 22 for Rs.43k with three year warranty, but it is not functioning since 25 August 22, 3 times technician came to replace part, but every time they use to find different issue, now they are asking me that they are going to change/ replace some other part, Already two times they had changed the parts, and still the issue had not been resolved, So they have now replaced my old TV set with a new one but the packing is of very poor quality seems to be like a refurnished TV set been hand-over. So there is no surety that the TV been replaced is of a new lot since the outside packing does not support the same .
This multiple repairs and several communication are giving me a mental setback and not been accepted by a brand like VU .
So kindly consider my above petition and arrange me a brand new TV set or else refund me the paid amount .
