Happened to me earlier in the season with a so called bluenose from Greenock. I was allocated Hamilton in cccs but was on holiday so arranged to swap for a St Mirren ticket which he said he'd been allocated but had another through his rsc. I sent him Hamilton ticket first class in post and he said he'd do the same with St Mirren ticket.
Anyway, day before the St Mirren game and still no sign of the ticket (trains etc already booked). He told me Rangers hadn't posted his ticket but he'd meet me outside the ground with his rsc ticket. Didn't show up.
Got one outside the ground anyway but he since blocked me on Facebook and wouldn't pay for my Hamilton ticket.
