I'm having this same problem. Can't log in, can't change password. And... this is my bad: I don't know my UserID. I have my log in email, of course, but... what do?
Well, I always try to contact support first, if support doesn't respond then you can take some further steps... CSFBC is their representative here, so you can try to write a PM to him.
Just complaining here will not get you far, you need to push a bit... write to support, a few times if it's necessary, contact CSFBC, and if you are persistent you will solve your problem... of course, if you are a "fair player".
Most of us experienced many issues & problems with casinos around. Sometimes patience & polite approach are the best things we can do, and of course, finding the right places & persons that can help you solve your problem.
