I think you're being a bit over dramatic here. Barber has said himself he's keen for supporter exchanges and often addresss issues personally and also releases FAQs. All I'm suggesting is that this question is added to the list in the way others get brought to his attention.
To be fair to Paul Barber he did get compensation for us Player users when the service was shocking. Might be worth asking him. That said I'd also write back and suggest Southern must know how much per person the club pays and they can surely pro-rater it for you.
