That happened to me once and I found out that it was from when I had ordered something from Victoria's Secret. You know how they offer you free magazines as a trial. Well, what they don't tell you is that after the trial is up, they start charging you, without contacting you to let you know or to see if you want to continue. I had to call about 5 different #s before I got it cleared up and even then I didn't get all my $$ back!
