Need a refund

when you contact adobe support per @John T Smith the first issue you will encounter is, did you cancel your subscription during the free trial period.  if yes, there should be no penalty.  if no, it helps to present a sympathetic case for why that did not occur.

saying you were billed without your consent is not a winning tactic because, if you acknowledge you had an adobe trail, you did give consent (though you appear to not have read your agreement when starting that free trial).
