Please contact your Event host about the refund policy or canceling your
tickets. Most of the events do not allow canceling tickets after it's
been bought, but to be sure
check the policies on the event page.
Unfortunately TicketGrind can't do that. TicketGrind is just the middle
man between ticket seller and ticket buyer to facilitate the transaction
process. All
policies for the event are set by event
organizer.
