Batteries on my AirPod 2 are not keeping charge. They run out quickly. Apple website shows $49 battery service via mail in. But it doesn’t show how it can be done. The Apple rep via messages wanted the date that the AirPods 2 were purchased. When I informed him or her they said it wasn’t correct and that they couldn’t assist further without me going to an Apple Store. The nearest store is 100 miles away from me. Do I have any choices if I don’t have my exact purchase date available? Thanks.
