I just bought 4 Leeds festival tickets, but i just read there is a ticket limit of 2.?

Hi, well i was in a huge rush so i didnt have time to read trivial things such as ticket limits, seeing as the ticket limit for leeds festival has always been 4 i would not have thought that was going to change! so i bought 4 weekend tickets! and they have taken the money out of my account given me order details e.t.c. So will it matter that the ticket limit is now 2? why was there even the option to buy 4 tickets if 2 is the limit it makes no sense, thanks
