Amazon India — fake product and bo addressal

I ordered a smart watch which tracks steps bp sleep etc it costed me something around 600 rupees.
The feature were really appealing this i ordered the watch. When i recievd the watch i did not know how to carge and start so i went to a shop to learn it. When i tried to connect it with the mobile phone it did bot connect. Again i thought i did not know how to connect so i went to electronics store and asked for help i went to 7 stores but no one was able to connect it. They said that this watch has connectivity issues and rhus it is not being connected. It was really disgusting. I am trying to call amazon but their number either comes not available someimes busy and half of the times they say the number is wrong. It is a disgusting product on the very first day the screen cane out and i had to fix it back. I dont want such a thing but they are not replying thus i cannot do anything. It is a fake watch and amazon is selling fake products.
