Olivia Dean has described the concert ticketing business as "exploitative" and rife with "inequality" after securing her fans a partial refund from Ticketmaster and AXS.
The star's comments came after some resale tickets for her North American tour were priced at 14 times their original face value.
Last week, the star wrote an open letter to ticketing companies calling the practice "disgusting" and "vile", and urged the company to "do better".
On Wednesday, Ticketmaster announced it would cap future resale rates for Dean's tour and was in the process of "refunding fans for any markup they already paid to resellers on Ticketmaster".
"We share Olivia's desire to keep live music accessible and ensure fans have the best access to affordable tickets," said Michael Rapino, CEO of Ticketmaster's parent company, Live Nation Entertainment.
