Just got an email from Merlin:
"Dear Mathew
On Friday 25 March 2016, our 12p ticket sale went live too early. This is the last thing we wanted, and understandably it left you frustrated and annoyed that your chances of winning may have been affected.
We could continue to apologise, but actions speak louder than words. We promised we would try to make amends if we could, so as a gesture of goodwill, we will be more than trebling the amount of 12p tickets available for 2016 - a further 4,000 tickets will be made available as part of the draw!
On Monday 18 April 2016 each person who registered to the site before the main sold out page went live on our website for all to see will have their details automatically entered into the draw which will be run by an independent adjudicator. You are one of those people, and there is nothing else you need to do to be entered."
Fair play chaps, excellent work!
