Event Timeline:
- on **th September I ordered a TV online(Mi LED Smart TV *A Pro ** inch with Android)

- On **th Oct I noticed some strange blue lines on the television. The same day I lodged a complaint with Flipkart.

- On **nd Oct I complained about it to Xiaomi.
- On **rd Oct service engineer was scheduled to visit, instead, he came the next day.
- On **th Oct he checked the television and confirmed the issue with a display panel and told he will be back in ** days with the new display panel, we argued on why repair and why not replace the tv.
To which he mentioned the warranty is not for the television but is of parts inside. So he won't replace the tv. For faulty parts, He will change it as per warranty.
I checked the bill and xiaomi website, for the first-year TV is covered under warranty.
- On **th Oct, I called him again and asked him for claiming a new tv under warranty to which I was informed, he does not and cannot replace tv. I was asked to contact the service center in Borivali. I tried that number for a few hours either the number was busy or went unanswered.

- on **th I logged a complaint with Flipkart as well to intervene, to which I was informed this is not something Flipkart can help me on.
