Granite Bay is part of Sacramento isnt it? What is your shipping address on the Order Details? If it is correct, email seller immediately, and they will redirect the package or send you another one. If you gave incorrect address, you can ask them to help. We dont know if you had the correct shipping to seller. Let us know. Dont contact Ebay yet.
Technically, Guam is not another country. It's a territory of the US.
I'd start with the seller. It was likely an honest mistake, and if so, they will work to get your item to you, or get you a refund. If that doesn't work, you'll have to go through eBay.
Do you know that it was misaddressed? If not, the shipper is at fault. Contact them.
yes
