This company charged 57.61 USD on June 4, 2009 to my Visa account, yet I never contacted them in any way. I suspect that they got my credit card number via a so-called Google affiliation. When I called the 800 number listed next to their business name, the company told me that they could not locate my record, and that I should contest that amount with Visa.
There are other similar unexplained charges on the same bill, by Blazingkeywords.com and Secret Grant Funding, who both gave me an email address to get a refund from and closed any account I had with them, and from Grant Masters, who closed my account and promised me a refund.
Note that I called Visa to have my account locked until further notice, and to mention that I am contesting the aforesaid amounts.
