If you're thinking about doing Cerebral Don't. I did it and had a horrible experience. The person assigned to my case was completely insensitive and unprofessional. I called and canceled the same day I had the appointment and THEY STILL BILLED ME! They make it nearly impossible to cancel in the first place and after filling out 3 cancelation forms and calling twice I thought it was taken care of. Well turns out that meant nothing as I had a charge on my account this morning. Criminal!
