How to Cancel and Delete Your Relume Account During Trial Period

To the support team: How do I cancel and delete my account? I did the trial and presented Relume as an option to my client, but have not received approval to use the tool and do not want to be billed for it. I am in the trial period now. Everytime I fill out a support request in the form online I get an issue error. (cenniskloote@augustodigital.com)
