No way to confirm if invoice is a scam
I received a four page invoice for "customs duty" by USPS mail which is somewhat comical if it is not a scam. I do not use a FedEx account and the phone tree will not allow me to proceed without an account number. i can't verify the bill because they have no email address bc no account. The website is seemingly designed to prevent all communication. Can I go to a FedEx office with this invoice or any other idea how to contact them to verify it?
