The telephone number is 866-279-0347, but trust me, they will hang up on you or leave you on hold for an indefinite amount of time.

Immediately after I entered my credit card account number, the Grantsforcitizens.org websit disappeared. I will call the phone number given to reach them, and if I have any problem, I will diffinitely report Grantsforcitizens to top level US government officials.
