I haven't tried to call, but it is not a good sign when phones are not answered. I usually like their customer service & enjoy wide range of wagers, but they are falling quickly from the top echelon on my list.
CARIB is so solid it's ridiculous. their server is slow or down during peak hours sometimes, but you should have multiple outs anyway. i requested a neteller withdrawal earlier today and the money was in my neteller account in less than 10 minutes. if i could only use 5 books, CARIB would be one of them.
