How important is customer support when registering with a bookmaker? Does anyone really pay attention to how they respond, or is it a minor issue? I've already had the unfortunate experience of "waiting forever for an operator", so I want to know where to go in advance.

Support is like insurance. You hope you won't need it, but when you do, it has to work. I had an experience where the operator took half an hour to respond, and after that, I immediately changed platforms. At https://1-xbet-kenya.com/registration/ , the situation was completely different. There, I received help quickly and without unnecessary fuss. This greatly affects the user experience, especially when money is involved. So yes, it's definitely worth paying attention to. Support is a sign of how players are treated.
