Complaint Review: U.S.Financial Resources

Was inquireing about grants to help with financial needs as I am a senior citizen and  have days left at the end of my income.  Got a call from someone, no name, telling me I was approved, and needed to charge me $3.87, gave a cinf # 135006.  a support telephone no of 1-800-558-0064.  An e-mail # of support@usfinancialresources.com  and I was to use mrgulsby39, password 29644..  The person on the like was not American and I really had a hard time understanding him.  I realize now that I should not have given him my credit card no.  He was saying something about another charge of $59.95 but I was not clear as to what it was.
