I signed up for MobileMe free trial and then decided I didn't want to use it. They sent me an email saying they were going to charge my credit card if I didn't cancel. So I went out to cancel and couldn't locate the place to cancel - so now I have a charge of $99 on my credit card... Could someone please tell me how on earth I cancel this service? There are no phone numbers or email addresses I can find to cancel this service! Thanks!
