If only I'd done my research on this guy! You'd think that someone who's been allowed to hang out on this forum for so long would be a good guy, but sadly not. He posted an advert for some bits for sale, and I took interest in a Titanium stem he was selling. He said he'd like bank transfer for the money, and he'd post it out before the end of the week - that was the 14th June. After a week, I got in touch to ask about why I hadn't received the stem, and he said he'd been really busy and would sort it. A week or so went by, so I asked again with a firmer tone to my message - no apology, just that he'd get it to me within a couple of days. He's now stopped replying to texts or pm's, taken my money, and never posted the stem.
EDIT: after quite a bit of chasing Kev did come back to me and honour a full refund. I can't fault him for his offer of a refund, but the journey getting there was long and painful. I think he needs to understand the expectation from buyers when purchasing through here really; you pay, you send ASAP, and then everyone is happy!
