I am player at Canbet and I advise you to contact canbet representative in this forum and I am sure they will solve your issue. Even Iam an old player at Canbet, they give me the casinomeister bonus.Contact them here via private message.

Regarding this bonus, I think you are alone bringing this issue. I did not see any posts from canbet new players complaining about the casinomeister bonus.
Good luck
