We were hoping the original poster was going to come back and explain exactly what happened and how it was resolved but they appear to have vanished.
To cut a long story short though we spent quite some time on the phone to McBookie who explained their version of what had happened (there are two sides to every story) and in the end they agreed to basically just pay the player off. They still felt they were in the right not to have to but overall it would be quicker and easier to say "take your money and go, and go now".
They are not unreputable or theives, they just don't tolerate fools gladly. If you are straight with them then they will be straight with you.
