The Consumer Council said that as of 1pm on Tuesday, it had received 24 complaints about the cancelled show – eight from local consumers and 16 from fans outside the city.

The watchdog said the total amount involved in the complaints was HK$63,613, with HK$6,700 the single biggest sum.

“The complaints included the organisers’ failure to reschedule the concert for consumers and disruptions to hotel and transport arrangements for attendees who travelled specifically to Hong Kong,” a spokesman said.

“The Consumer Council urges the organisers to handle the matter properly, including considering different alternative solutions.”

The group’s record company, B’in Music, announced late on Monday that the show originally scheduled for March 24 would be cancelled, while an additional performance on March 29 would be added as part of the “Mayday #5525+1 Live Tour” in Hong Kong.

In a statement on social media, the five-member, all-male band said the decision followed an internal assessment to “ensure every show can be presented in the best possible condition” and allow fans at each performance to fully enjoy the concert experience.
