I received a notification from a group call Graham Group, LLC and they stated I was due a cash reimbursement. They asked for a copy of a valid id. They also stated that for anyone believing they were scammers to go to www.myflmoney.com, go to credentials and it would take me to the appropriate State of Florida licensing page. They listed their license number as A2400037. They had my former address and listed the last four digits of my SS#. How does one research to find out if a company is legitimate?
