the official leeds and reading website states that only seetickets, Lastminute.com, Ticketline, Ticketmaster, Gigantic, Ticketqueen and Voyagenbus.com are official venders, and they [restival republic, i imagine], cannot be held responsible for any purchases through unauthorised vendors.. there's a few threads about people buying from touting sites, such as
sosticketmaster here and
here, and
readingfestivaltickets, so you might have been conned..
