Basically a member made an offer on something i was selling, we agreed a price and moved to pm. After receiving their address and agreeing that they would pay the next day i've heard nothing from them, or had payment. I've pm'ed them and they've been online several times since but i've had no response.
I'm inclined to leave them negative feedback as they've wasted my time, but what if they decide to leave me some in return? I don't want any black marks on my record but i also don't want them messing anybody else about. So my question is, is it worth it?
What you reckon?
