Amazon India — Amazon basics TV warranty claim issue

I have been working with Amazon in claiming warranty for Amazon basics TV purchased 10 months ago. It’s been a month and the issue is not getting resolved. All Amazon does is create a ticket for service providers to fix it and service providers cancel it or call and ask for money to replace mother board. Amazon said they will replace the TV if service provider do not fix in 3-5 business days and every time I call back after this window, they just open another ticket. Amazon customer service is useless. They are unable to fix the problem and they hung up my phone calls. While the TV is under warranty, why can’t they replace or refund it even after 6 attempts to fix it. This has caused a lot of frustration with numerous calls and no sight in getting the issue resolved. The email id customer service gave ([protected]@amazon.in) is no longer valid. How could they even share me this ID if it’s no longer in use?
