I also pay attention to live support from the casino I play. Sometimes what is annoying is when we want to ask questions related to problems to support but have to wait in line for a long time.
casinos with live support that are fast in providing solutions are very enjoyable. they are all almost equally friendly, but not all the support that casinos have is fast.
Live support usually doesn't help at all.
They're not really know about the casino they work for, if you ask something that stated on their terms, they can answer it. But, if you ask something like case by case basis, they can't answer it.
The numbers can be faked, trustpilot isn't a reliable source though.
