Nokia — Nokia 65" tv

I bought your product from Flipkart on 6 april and also bought extended warranty and within 1 month I t stopped working. Ther was no led light atall and it was not turning on atall. I contacted provided customer care details. Since then there are 4 telephonic troubleshooting 5 engineer visits. They have opened my brand new tv 5 times to change wires, motherborad, software updation and number of parts and till today its not working.. worst product n service.. i wasted my hard earned money.. i dnt want to defame you on social media but hoping to get either replacement or my money back
