That isn't very fair. I am sorry that you missed out on getting a ticket. ,
however, the tickets were on general sale yesterday, that means that anyone can buy them, if they are lucky enough to get through. If the band wanted the concert to be a UK only gig, then they would have asked for it to be organised it that way. Thankfully for people outside the UK, the band are not that mean! everyone had their chance to try for tickets.
