Not sure if it will help but sometimes charging overnight on a 5W charger can get it going if the battery is just really dead. Probably the easiest way to ensure you’re getting 5W is a USB A to C cable connected to a PC or laptop. If you have an older wallwart with a USB A port it’s probably 5W charging as well. Could be worth a shot before sending it back.
Reading this I should live like a medieval peasant and only eat potatoes, onions, and root vegetables and drink nothing but beer. I’m kinda down with that.
