The organiser announced on Monday that the March 24 concert for the band from Taiwan had been cancelled.
Mayday was originally scheduled to perform in Hong Kong on March 24, 25, 27 and 28 as part of its 29th anniversary tour.
The decision, the organiser said, was made “to ensure that all performances are delivered in optimal form, allowing fans at each concert to fully enjoy the special moments of the birthday celebration”.
Refunds will be issued to those who hold tickets for the affected show, the organiser added.
As of 5pm on Wednesday, the consumer watchdog had received a total of 111 complaints related to the cancellation.
Forty-two were lodged by local consumers and the rest by non-local customers, the majority of whom are from the mainland.
The complaints involve a total sum of HK$296,194, according to the council.
The largest individual claim from a local consumer amounted to HK$6,700, while the highest from a non-local complainant was HK$8,000.
Grievances among local fans largely stem from the organiser’s failure to offer priority booking or ticket exchanges for other performances.
Non-local complainants, meanwhile, expressed dissatisfaction over the lack of compensation for travel and accommodation costs.
In a statement on Tuesday, the Consumer Council said cancelling individual concert dates would disappoint ticket holders and could disrupt the travel plans of visitors coming to Hong Kong for the show.
The council urged the organiser to manage the situation appropriately, including considering alternative arrangements for affected fans.
It also advised concertgoers to stay updated through official announcements and to keep relevant transaction records.
Following the cancellation of the March 24 show, Mayday has added a new performance on March 29.
Tickets for the March 29 show went on sale at noon on Wednesday.
