Master Control Calendar

I would give this Tissovo a zero if possible! I received the watch on Aug 4th it stopped working on Aug 6th ( a day and a half before it broke!) no matter how much I wind the watch it wont move. I did not drop it or anything like that! It just stopped working while I wore it! Tissovo customer service is horrible, they wont respond even though I sent them multiple messages! I’m not sure what to do next?!
