Lost my case

Hi, I bought your AirPods through an importing company that apparently doesn't import your AirPods, called "gomobile" in Israel, and I recently lost the case to my AirPods, meaning I can't charge them. I would like to know if I could get a new case, since I've bought the AirPods less than 6 months ago, instead of buying new ones. I can send you pictures and proof that I've bought from you.
