I was the victim of a scam. But can I flip it?

I'm in a crazy situation here. I voluntarily gave someone my debit card and PIN number because they promised to put money on there. I cleaned out my account gave it to the guy and sure enough money was put on there. He promised to give me my cut this morning but he hasn't called or responded to my text messages. In fact, the only time he contacted me was to ask me to take off the limit. Now, I have a overdraft fee of $1 and $1,300 is processing and is going to be in my account in two days. What I'm planning on doing is canceling his (my old ) debit card, get a new one and keep the money. I also put the limit down to 1 dollar so that he is limited to what he can do. Is this the right way to go about the situation? Am I doing anything incriminating?
