Ticket vendor Cityline has denied any system irregularities involving online sales for the highly anticipated performance of K-pop girl group NJZ, formerly NewJeans, at ComplexCon Hong Kong next month, after fans complained that a glitch had changed the dates on their passes.
The Consumer Council said it had received nine complaints related to the purchasing of ComplexCon tickets, involving a total of HK$39,479 (US$5,070), as of 5pm on Tuesday.
The pop culture festival’s organiser also said there had been “suspected anomalies” linked to online sales, with new ticketing arrangements being put in place.
Earlier in the day, Cityline issued a statement on its website saying that it had received a number of inquiries from customers about tickets for the event.
NJZ is expected to perform on the last day of ComplexCon, which will run from March 21 to 23.
“We have reviewed the transaction records with system logs accordingly and can confirm no [irregularities were] found,” Cityline said.
The company added that customers with similar inquiries should send a copy of their transaction details and confirmation emails to cs@cityline.com.
A day earlier, dozens of fans took to social media soon after a priority sale for select ComplexCon tickets began at 4pm and said that attempts to buy ones for March 23 saw the date suddenly change to one of the other two days.
Some users wondered whether they had clicked the wrong date in their rush to get tickets, while others insisted they had followed all the steps correctly and still received passes for the wrong day.
“This is crazy! I was trying to buy NJZ tickets for ComplexCon on Cityline just now – I selected [March 23], but after paying, a system bug changed it to [March 21],” one user said, adding that she had seen other posts from people experiencing the same issue.
“I’ve already emailed Cityline, but they’re refusing [to issue] a refund. I’m prepared to take further action.”
Her social media post has since garnered more than 600 likes and attracted dozens of comments from other users saying they had similar experiences.
“There is indeed a bug – but I spotted the date was changed to [March 21] right before I paid, so I caught it in time,” one said.
“How is this different from a scam?” another user asked.

Event organiser Complex Chinese announced new ticketing arrangements following the online outcry, saying passes would now be sold in phases.
“Based on the feedback we received, there were suspected anomalies during the [earlier] ticket purchase process. We have promptly communicated this to the ticketing platform, Cityline, for further action,” it said.
“As we do not have access to their system, we are unable to directly investigate and determine the cause of the incident.”
The first stage of the new ticket arrangements will start from 4pm on Wednesday, with various types of single-day passes for only March 23 being sold for prices ranging from HK$988 to HK$1,788.
The tickets will be sold on several platforms, including Trip.com, Cityline, Maoyan and Ctrip.
Complex Chinese said sales details for other ticket types and the remaining festival days would be announced later.
Other tickets will range in price from HK$388 for just marketplace access to HK$4,988 for a three-day VIP pass.
The Consumer Council said on Tuesday that it had received multiple complaints over the suspected glitch, urging customers to check whether ticketing platforms had any refund or exchange policies.
They also urged consumers to contact vendors as soon as possible if they discovered an error in their purchases.
The watchdog said cases with sufficient evidence would be raised with the relevant merchant on behalf of consumers to seek follow-up through mediation.
This year’s ComplexCon marks K-pop band NJZ’s first performance since its five members entered into a legal dispute with their former agency HYBE last April.
The group made its debut under the name NewJeans in 2022 and quickly shot to fame with its distinct, Y2K-inspired sound and choreography, along with consecutive number-one hits such as Attention, Hype Boy and Cookie.
Last week, the band announced it would perform under the new name NJZ and be appearing at ComplexCon in Hong Kong next month.
