Even still, be careful. Definately DO NOT give any form of information to them over the phone ( little stuff like your address and name is probably fine, but do not give them your SSN ( if you are in the US) and , obviously, dont give them any form of bank account or credit card numbers.)
I'm always careful with this sort of things, phone scams are increasing at an alarming rate here in Chile. Anyway, the whole thing was real :icon_bigg, so in a few days I'll have my 1000 dollars.
