I hate books that call also and will never talk to them, the only exception is heritage called once I got a free 500$ acct from them last year and cashed it out after rollover for around 900$ so I was "okay" with that call but, I NEVER give my number out to them , if they say thay have to have it I find another book, but that's just me...
I think I figured out how these books get our addresses and phone numbers. They do Zaba searches and grab our info from there. It used to piss me off when the books call but they aren't pushy like the newspaper telemarketers so I just chalk it up to them just trying to do a job. If I see a 305 number or an area code I don't recognize I just let it go to voicemail and that is the end of it.
Isn't BetDSI somehow affiliated with Bookmaker?? They've been calling me at least once every two weeks since April, sometimes as much as three times a week, offering a "100 percent bonus for a $100 deposit". They must really want my $100!!
