For everyone who hasn't been able to get a full refund this is for you. Cerebral will give you a full refund if you threaten legal action & report them to the BBB. Forbes did an article about their deceptive business practices & unclear pricing (note: pay attention during sign up it may switch from monthly to weekly) & found that users who threaten legal action against Cerebral got full refunds quickly. Also, if you paid with a credit card look into disputing the charges.
