A bit of an alternative view - perhaps something has happened to the seller?

I was selling some things on ebay about a month ago and miscarried. All transactions were posted but I had one email from a buyer where they complained that a "small" was actually a 6 rather than an 8 (apparently in tiny-clothing land, 6 is an XS, 8 is a S - heck I have never been smaller than a 14 so everything below a 10 is a small to me). Turns out they wanted a XS, so the top was bigger than they expected.

I knew I had the email, but couldn't bring myself to log in to ebay and deal with it and other stuff, like leaving feedback, because I had just miscarried. In fact I wasn't up to logging on to ebay for about a month, I just was too over everything for that time in my life. But I figured no one is really hurt, and really, I couldn't give a stuff about negative feedback in the grand scheme of my life at that time (as it turns out the woman who bought the top left positive feedback anyway).

So maybe think of it this way - you haven't been ripped off, but rather lost the opportunity to buy something. Maybe the person who isn't replying has other stuff going on in their life. Sure maybe they are lazy, but maybe its something else.

Just a thought
