From my experience they're pretty available! Had a similar situation a while back, logged in late and still got connected to someone quickly. I checked through casino gamwiz casino uk support section directly and the live chat was right there and active. Got my issue sorted in maybe 15 minutes which was a relief. Response time was solid, no long waits. Not sure if it's literally 24/7 every single day but the times I've needed help outside normal hours it's always worked out. Worth just opening the chat and seeing — usually someone picks up pretty fast!
