Crossbeats — Watch is not working properly and charging does not work anymore

I've bought this watch around 5 months ago . It was a new launch when I bought it in Amazon . Orbit Styl Call ( adavanced by calling smartwatch).
I've used it only a few times from the day I bought it . Only after few usage it does not work properly and charging is not working, I've also tried many other adapters for charging the watch it doesn't work either that way . So, kindly tell me what to do next or replace my watch for new properly working watch.
Thank you.
