I signed up cerebral and while the idea is great they need to work on their transparency. The price is not clear and I was charged way more than was initially understood. There is no one you can talk to over the phone so the cancelation process is done solely through email. So after my initial email and many more back and forth I am only going to receive a 30% refund for filling out thier forms and for making and appointment that was canceled less than 24 hours after signing up.
