Used SeatGeek for the first time to purchase Stevie Nicks concert tickets. When we got to the gate, we were turned away because our tickets have already been used. With a calm head, I called SeatGeek and they took care of the situation immediately. Sometimes the seller of the tickets accidently double sells the seat on several ticket sites. Out of SeatGeek's control but it does happen. Customer service agent Jack in Portland quickly got me new tickets and we were in our new upgraded seats just as the concert started.
