My friend bought 4 tickets from Ticketmaster to a gig but the organiser decided to cancel, so TicketMaster gave her a full refund.
I bought 3 of the same tickets from SeeTickets but SeeTickets kept £24.70 and gave me back the balance.
They cited T&C's so they can keep the booking and transaction fee.
Never using them again and deleted thier app. Stick to ticketmaster or ANY other seller!
