This is why I have never called a book from my cell (don't have a landline). Always put 000-000-0000 in as my number when it is a required field to sign up and if I absolutely have to call them, I go to a payphone, as much of a hassle at that is.
After I opened an account and deposited at SBG, I had to call to confirm my account before I could make a bet (idiotic policy). I went to the mall and used a payphone. The CS rep asked me if I had a phone number and I flat out told her that I did but I wasn't going to give it to her because I didn't want to be called and if that was a problem then close my account and send my money back. She relented. No way they turn down your money because you don't give them your number.
Just call Anthony in Bookmaker Customer Service (don't talk to anyone else) and ask him to adjust your profile so the software will not pick up the phone number listed there and send it to marketing anymore. You can say Wilheim told you to call.
dude, just play along, talk to them, get the info, keep em on the phone for half an hour, give em fake transfer numbers, stuff like that...... if they keep calling u, its their loss.
