Scammed for 10m

Briefly explain the trade:

I posted on his thread that I wanted to buy a 30-day upgrade off him, he agreed, got on MSN very fast. Refused to go first so I did. Did it in clan wars red portal since he had a 25k trade limit or something. Seemed fishy right there, but I figured that he could be trusted. On MSN afterwards, he kept saying that he was running short on time, wanted me to apply it instead of him. I asked him to, he stalled for a few minutes, then gave me some random upgrade information that would apparently work through paybyphone. He said it would work with an hour delay because of runescape maintenance. Don't think he was lying about this, as runescape was really going through maintenance issues, as Jagex posted. He asked for a vouch so I gave on thinking I'd be a member within the hour. I wasn't, removed my vouch, he hasn't been on MSN since, PM'ed me with excuses that seem like obvious lies, he's still viewing his thread fairly often.


Proof that you were not talking to an impostor: is in the following screeny

I think this is sufficient.
If he wants to dispute he can show proper evidence.

Edit: Also a false voucher.
