That doesn't sound good. The usual thing to try when a fitbit misbehaves is a restart but I'm not sure it will work if it's not charging. The instructions are:
- Plug the charging cable into the USB port on your computer or any UL-certified USB wall charger.
- Clip the other end of the charging cable to the port on the back of the tracker. The pins on the charging cable must lock securely with the port.
- Make sure the button on your tracker is aligned with the button opening on the charging cable. You’ll know the connection is secure when the tracker vibrates and you see a battery icon on your tracker’s display.
- Press and hold the button to restart your tracker:
- For Charge 2—press and hold the button on your tracker for 4 seconds. When you see the Fitbit logo and the tracker vibrates, the tracker restarted.
- For Charge 3—press and hold the button on your tracker for 8 seconds. Release the button. When you see a smile icon and the tracker vibrates, the tracker restarted.
- Unplug your tracker from the charging cable.
If it won't restart, or the restart didn't help, then I think it's best to contact customer support. If they can't fix it then they can check your warranty status and advise on your options. You can contact them via contact.fitbit.com
