Fastrack — Smart watch ( FASTRACK REFLEX CURV ) is not working

Address:

SABLE NAGAR RAILWAY COLONY KURLA EAST MUMBAI 400024

I have purchased a FastTrack smart watch, and after a few months, the watch is not working, and the screen is not working. I want a replacement product. I've been attempting to file a complaint and sending emails to customer service for over three months, but no support or assistance has been provided by the company, nor have I visited a nearby Titan store.
