ha ha, i love this..
ooohhhh, the indignance!, the outrage!, the horror of it all!... yet YOU were quite happy to become one of these CONNIVING, DEVIOUS and EVIL people when you thought you were going to SCAM a few hundred quid off someone for nothing, weren't you??
if he'd made a genuine mistake, did you think he wouldn't have noticed and you would have got away with it?
he had your bank details...duurrrr!
if someone pulled a stunt like you did, with me, i would clean them out - for spite.
you deserve all you got.
