Sportbook.com is an on-line gambling site. I requested a check for my winnings. I had to fax my drivers license, social security to them and I received a check two weeks later. I deposited the check into my my Mom's account and the check came back not paid. The check is stamped Return Sender-S Refer to Maker. I called Sportbook.com and spoke to an agent named Roger Jimenez located in Costa Rica. He told me to fax a copy of the returned check to the verification department and they would recredit my account. I could then request a check and they would mail me another check.
