This just sums up the incompetence of PandA.
As I understand it, those that have commented so far have already payed and have the receipts to prove it. I think it's reasonable to assume most of the receivers of these letters have already payed up.
If it was me, I'd leave it alone and wait for PandA to take me to court. Good luck with that PandA.
If I was part of the trust, I'd be shouting this from the rooftops, national press etc. Pressure must applied to show PandA what they really are.
I wouldn't wish that company of IP's on any other football club, ever.
