UNAUTHORIZED CHARGE TO MY ACCOUNT

I am furious- just noticed my checking account was charged $74.98! A few days ago and I just saw it! Naturally they are closed because it's the weekend. I am soooooooo mad. I will be at my bank on Monday with a complaint and see what I can do about this. I can't even take the stupid InstaFlex because (unknown at the time I ordered the trial bottle) it would interfere with medicine I'm on. Grrrrrrr.
