If you're certain you or a family member did not order anything from Adobe, maybe your card was compromised without your knowledge. Contact your bank immediately. Adobe cannot help you because they are victims, too.
Your bank will probably ask you to sign some legal forms before they cancel the account and turn the matter over to law enforcement for fraud investigation.
