Ticketmaster's president has admitted to "stuck transfers" following a ticket delivery failure last Friday, drawing fresh criticism over the company's reliability. A separate report used the incident to highlight the risk that comes with placing all trust in one ticketing service.

The trouble comes as a reseller listing a Bruno Mars ticket said she was caught off guard by the fees Ticketmaster added on top of her listed price. Rival SeatGeek, meanwhile, unveiled TourIQ, a forecasting tool aimed at live event sellers, positioning itself as an alternative at a time when faith in Ticketmaster is slipping.
