Ticketmaster's president has confirmed "stuck transfers" following a ticket delivery failure last Friday, raising new concerns over the company's reliability. A separate report cited the outage as evidence the risk that comes with relying on one dominant ticketing provider.

The trouble comes as a reseller listing a Bruno Mars ticket said she was blindsided by the fees Ticketmaster added on top of her listed price. Rival SeatGeek, meanwhile, unveiled TourIQ, a predictive pricing tool aimed at live event sellers, positioning itself as an alternative at a time when trust in Ticketmaster continues to erode.
