Inspire 3 not charging

[Spice2]

I tried to charge my fitbit inspire 3, but it said I have to update software.   When I tried to update software said phone needs to be fully charged.

I then disconnected fitbit from App now it will not sync 

----

 have managed to update app, but fitbit watch is dead. It is not charging or syncing with phone

Moderator edit: clarified subject.

here are the support contacts I've gleaned over the years on the forums.

when there is someone available, chat is an option. Phone or X/Twitter works well, too.
