I hired Mark to do a graphic design job for me. He told me he'd be able to do the job no problem, and that it would take him just a few days to finish the project. He asked that I paypal him money to start the project.

Mark then decided that he didn't want to do the job, and that he was also going to keep my money.

Beware of this guy, he doesn't deliver on his promises and he will keep your money.
