Getty ImagesTicketmaster "may have misled Oasis fans" with unclear pricing when it put their reunion tour on sale last year, the UK's competition watchdog has said.
The Competition and Markets Authority (CMA) said the company may have breached consumer protection law by selling "platinum" tickets for almost 2.5 times the standard price, without explaining they came with no additional benefits.
"This risked giving consumers the misleading impression that platinum tickets were better," it said in an update to its investigation into Ticketmaster.
The CMA says it is seeking changes to the way the ticketing platform gives customers information and how it does so. Ticketmaster has yet to respond to the report.
More than 900,000 tickets were sold for Oasis's long-awaited reunion tour last summer.
But many fans were left out of pocket, when standard standing tickets advertised at £135 plus fees were re-labelled "in demand" and changed on Ticketmaster to £355 plus fees.
Ticketmaster has subsequently denied using "dynamic pricing" to manipulate the prices.
"We don't change prices in any automated or algorithmic way," the company's UK director, Andrew Parsons, told MPs last month.
He maintained that all prices are determined by artist teams and promoters - although, in the case of Oasis, the promoter, SJM Concerts, has ties to Ticketmaster's parent company, Live Nation.
The CMA did not comment on the issue of dynamic pricing, but said that Ticketmaster made it difficult for Oasis fans to make "informed choices".
For example, it said, customers did not know that there were "two categories of standing tickets at different prices, with all of the cheaper standing tickets sold first".
This resulted in "many fans waiting in a lengthy queue without understanding what they would be paying and then having to decide whether to pay a higher price than they expected," the CMA continued.
The watchdog acknowledged that Ticketmaster had made some changes to its business practices since the Oasis sale last August.
However, it said, "the CMA does not currently consider these changes are sufficient to address its concerns".
"We now expect Ticketmaster to work with us to address these concerns so, in future, fans can make well-informed decisions when buying tickets," said Hayley Fletcher, interim senior director of consumer protection.
The BBC has contacted Ticketmaster for a response to the CMA's report.
Oasis's tour is set to kick off in Cardiff's Principality Stadium on 4 July, 2025.
