Update [April 30 2014]
The refund check (Now cancelled)Sent in Feb turned up today.
 postmark confirms it was sent in Feb and the check number confirms with what ken said it was on pm. So I can't blame him for this delay. The replacement check should arrive soon.

If ken could have just communicated this postage it would have avoided a whole rigmarole for the past 2 months.
In any case I unreservedly apologise to ken in light of this check arriving when all the evidence was pointing to a scam.
