The quality of a casino's customer support is obviously important for me, but I don't really mind if I have to wait a couple of hours or even days.
That said, I've never had to wait long before I've had my support requests dealt with. Especially not at the current website I'm playing, Crypto-Games.
Other casino's might adhere to offer support on business days only and I think that's also reasonable.
I'm with you on this. Customer support is always tricky business. Obviously, with money involved, customers get finnicky when support requests aren't handled immediately. Every passing day seems to trigger increasingly emotional responses and the humans on the other end of support can sometimes be turned off by impatience and lack of clarity with issues. On the other hand, I probably dislike even more those instant responses that don't seem to understand the actual issue: you get a generic tailored response that doesn't help the problem and only causes more frustration.
The best customer support probably starts with a detailed FAQ as a first line of defence. And a good customer support knows it needs trained, knowledgeable staff who know the mechanics of crypto, who know how the site works. I play at CGN too and probably have only needed to reach out once. Issue was resolved quickly and correctly (missing deposit), not many words exchanged. Works for me.
