Seems we are missing some details here.

In your original post it says you posted a wanted ad. And that the seller sent you an email letting you know he had what you wanted and to call him. When you chose to call back the item was sold.

It does not sound like any exchange happened to make any sort of agreement one way or the other. If he just sent an email saying it had one and to call. How does he know you are interested in his item. You call the number and it is already sold. Well, tough noogies, you missed it.

If however, you exchanged a couple of emails with some sort of sales agreement that BOTH of you let each other know they agreed to then the seller is a giant nonfunctional male sex organ.
