Ring Alarm Keypay (Gen1) Not Charging

My gen 1 keypad stopped charging after battery was fully drained. When I plug the charger, the red and green light comes on and stay solid. Status on the app shows no battery. When I unplug, nothing happens. I left it plugged in over night but seems like it did not charge the battery. How do I fix it ? I dont see any chat option with customer service not do I see any email option. Please advise. Thank you.
