Earbud Case Flickering Nonstop

Hello,

I have the EP-T21 in pink, purchased from Amazon.

My earbuds are suddenly refusing to pair and the two green electric lights on the front side of the case are flickering wildly. They never stop. I’ve tried clearing the pairing list, putting them back in the case and trying again, and restartin g my laptop and phone (which I use the earbuds with). Nothing works. Anyone else having any similar issues?

EDIT: I contacted customer support with my order number and they wanted a screenshot of my purchase. I can’t get one, because they were a gift. Is there any way to get around sending a screenshot?
