Gonoise.com — Faulty product and zero customer support

I filed the complaint the same day I recieved the watch about its laggy user interface, no notifications issue and half letters case.
They asked me to submit video and I did same day
Later on I called them back next day to know the update but they told me that u will recieve call back in 10 mimutes
Now after 4 days approx I called them and they are demanding me to be a f...g video Grapher
I told them I don't hv another device to do same and they don't care.
Now I m left with a faulty aur useless watch and worse customer service experience.
They tend to compete in market with so many dissatisfied customers
Literally there owner and management has some issues
