First, ask to your wife,
Due a bad economy time, can think also in a scam from someone try to ask you a money, no wife at home, farang scare lost car, farang pay...
Monkey think.
So, if wife doesn't know anything, wait and don't pay to nobody, if they came back and asking again, call main office bank for question. If they can take your car, they will do, not just asking.
