I received a reply to a question about a package that has been showing "Shanghai Airline Transportation" since 4/24/20. The reply said it is delayed. How can a package be delayed for almost 3 months?????? The seller I am returning the product to won't refund until they get the package. $56.50 is what I am owed. I feel this package is lost and I would like to file a claim for lost package. Please advise my next steps.

Sincerely,
Lynette King
