A SCAMMER from Thailand is using this number, he is telling you there company is going out of business and they are going to give you money back, some how they make it look like they deposit 2000 in your account and want you to send them the amount that is over, it's just a way to steel from you

Here are two points:
(1) Why would you give out your personal banking information to anyone who calls you?
(2) You are owed no money, but you gave them the information anyway?
