I called the number on my statement and waited on hold for a while. The woman I got ahold of wasn't terrible and she said she would refund the $29.95 and cancel my membership. She gave me a confirmation code. I let my bank know and they said they are well aware of Myfitness and their scam with grant writing express. They will process this as a fraudulent charge if the money is not returned to my account within 30 days or if I am charged again. I will also call the number for GrantWritingExpress that someone listed above to make sure that I have been removed from their and all of their affiliates' systems.
THIS IS THE DEAL: Apparently, when you get the free cd, you are automatically signed up for the monthly program of $74 something (which I was aware of and cancelled before my 7 day trial was over). ALSO they sign you up for MyFitness, some online fitness thing that none of us have ever heard of. You have to cancel that SEPARATELY, which you do by calling the number on your statement. (800-576-941). When you call, get a confirmation code from them and check your account activity regularly to be sure the money is refunded and is never taken out again.
From now on, no free trials, as recommended by my credit card company. As they put it, it's never actually free.
