After checking my Visa transactions, I found out I had a charge of almost 40$ of a company I never heard of... Found out, after calling, that Classmates.com gives your credit card information to them and they charge you without your consent. I did not get "Andy" (see other complaint) but "Regis" and he confirmed that they would credit my account, no fuss.
Thanks to all those who makes this site possible. It helps alot!!
