Boat — Warranty Scam

My Boat headphones stopped working a couple of months ago. I have sent it to Boat for warranty twice. Twice they have claimed "it is working fine" and sent it back to me. Ticket numbers 27551179 and 27991835.

However, it is not working. It does not charge. It does not power on. The indicator light does not light up. I have tried with many different chargers, cables, plugpoints.

I have also contacted all three service centers in my city listed in Boat support website. All three have told me they no longer provide service for Boat products due to "technical issues". This is highly suspicious. It looks like their warranty service is a scam.
