Glourious Model O suddenly doesn’t work anymore…?

So I haven't played for about half a year now and wanted to get back on my PC when my Glourious Model O mouse suddenly stopped working… a few days later I tried again and it worked normally but only for about half an hour, then it turned off and that was it…

I can't get it to start anymore, it doesn't charge, it doesn't do anything.

It's a wireless mouse, if that helps, but the cable doesn't work either… what should I do?

I never threw them down that often or anything, it's just like that from now on.
