Dead battery and not charging

My ring doorbell gen 2 battery completely died and will not charge. I did everything that was recommended and nothing. Just the white circle continuously. I called support and they tried to help me and then said because I let the battery completely die the doorbell is basically trash. The doorbell worked perfectly before this. I had just been extremely busy to charge it with my fiancé in the hospital for almost 2 weeks. I just can’t believe my ring doorbell is now no good because the battery completely died? Please tell me I got the wrong information and I can still get it to work. Thank you.
