The consumer watchdog on Monday called on indoor playhouse operators to ensure the design and layout of their facilities are safe, and to clearly list out terms and conditions to avoid disputes.

The Consumer Council said it had received a complaint about a child suffering a forearm dislocation and a wrist fracture from a fall while navigating a rope tunnel at a playhouse, and that a request for a refund and compensation was initially met with "ambiguous responses".

The venue involved only proposed compensation of HK$3,000 after the watchdog stepped in, but the child's parent had yet to accept the offer and was considering legal action.

"The council would like to remind the industry that indoor playhouses must follow stringent safety standards in terms of game design and venue layout. They should also properly assess and mitigate any safety risks and provide sufficient safety measures to participants to ensure a positive experience for both parents and children," the watchdog said.

Other complaints included a toddler playgroup centre providing unclear terms and conditions to use complimentary playtime offered alongside a course enrolment, and another members-only indoor playhouse resetting a customer's account balance to zero without prior notice upon the expiry of the one-year membership period.

"The terms and conditions of use should be clearly stated, and flexible pricing policies are recommended to manage expectations and minimise disputes between traders and users," the watchdog said.
