Used wrong e-mail when signing up for free trial

Is there a way how to change my trial e-mail to which i receive instructions regarding it ? I noticed i had made a mistake only at the very end when it was too late, this way i wont even know how to cancel it since instructions tell me id need my e-mail which was wrong.
