Well there you go
1st that phone it is NOT from the US
2nd it was bought through a third party (amazon)
3rd The ad says NO WARRANTY
4th you MUST contact the seller and ask him/her where is this phone from, and ask for the receipt or whatever its required by that Sony Xperia Care to get it repaired.
I understand your frustration but this is not a Sony issue but you and the seller, contact Amazon, they might be able to mediate this problem.
