Keep getting illegitimate buyers!

I listed my first ad on Ebay the other day and within like the first few hours of it being up Ebay told me some one had bought my item. I was quite surprised but also excited with myself that it had been that easy...

So I confirmed the order then messaged the buyer saying I'm glad they liked the camera etc etc and how would they like to pay.

 

Well the buyer returend with a very 'odd' message, asking me to talk to him on his email addreess (a very dodgy email address).

In the end I just cancelled the ad and re-listed it. (so my fees roll over to the new listing, right?)

 

With the new listing pretty much the exact same thing has happened. So before confirming anything this time, I messaged the buyer and again got a dodgy message back, so I AGAIN cancelled the order...

 

My question is, WHAT DO I DO NOW?!?

Considering just giving up on Ebay now.

Also how do I avoid getting these cancellation fees, because I am not paying money just becasue some fake buyer has stopped my Ad

 

Thanks, Lucas.
