I ordered tickets for the roni size gig from songkick but they never arrived, luckily I contacted songkick for assistance from the email address they provided where they said they would have canceled those tickets that didn't arrive and send new tickets to the box office. They also said that they would have sent me a confirmation email for the new tickets, but that email never arrived. Eventually the tickets were sent to the box office and we were able to see the gig but I don't think I will buy from songkick again after this experience unless they start sending e-tickets.
