Sky lounge New Year Party Scam

Unlike what they promised, they didn't have any DJ or even their own music. They simply put a loudspeaker for FML's music. Music ended at 11:30 and there was no New Year Countdown. Food was shite as well. Couple passes legit costed 4k+ and we got nothing that was promised. It can legit be classified as a scam now. Is there a way that we can raise a complaint/ grievance somewhere and/ or review bomb them? This is the one in Seasons Mall, Skye Rooftop is the real name
