4 weeks ago a member of this forum offered to sell me a small component and I paid him straight away. After 2 weeks it hadn't arrived ao I sent a PM in case he had forgotten. He responded almost immediately saying he had been busy. I know what that's like so I didn't worry about it. Another two weeks passed and still no part and now he's ignoring my pm's. I know he's been online from his profile.

It's a silly small amount of money but there's a principal at stake. Any suggestions on how to either get my part or get my money back?
