You need previous purchase history. Buy a ticket for the WBA game for £9 on your account first.
Has anyone fallen for this yet?
You are asking why it's not working. It has been pointed out that you need previous booking history and you have been told how to create the previous booking history. I can't say it will work but I can say that I'm 99% certain it will do. Tickets for Hull were in high demand and their is pretty much no chance that you will find someone offering one in the away end and unless you know someone who can get you in the home end (which I doubt, otherwise you wouldn't be asking how to get yourself a ticket) then the only option you have is to try it and find out.
Nice try ?
