Attorney General Andrea Campbell said dozens of people reached out to her office to complain that they couldn’t get a refund for Friday and Saturday’s shows, which won’t be as long now due to the lack of openers.

“After hearing from nearly 200 consumers who were struggling to obtain refunds from Ticketmaster for Ed Sheeran’s shows at Gillette Stadium this weekend, my office jumped into action to demand that consumers be provided a clear path to get their money back if they no longer want to attend due to significant changes to the lineup,” Campbell said in a statement.

The attorney general said she sent a letter to Ticketmaster “demanding” that the company make an exception to its policy that usually allows artists to cancel or change their opening acts without having to provide a refund to concertgoers.
