I just signed up with Diamond Sports as they were offering 100% bonus on your first deposit. I deposited $100 expecting $100 in free play money or bonus. It doesn't show up for a day, so I email them and they say they can only offer me 20% of the deposit, when it blatantly says 100% sign up bonus on their opening page. To top it off, they have some of the worst odds out there and now I have to wait two weeks to take my $100 back out.
Do not use Diamond Sports!
