customers service email/phone number?

Is there any phone number or customer service email for 7sage? I emailed them over a month ago when I cancelled by subscription, but still got charged and was seeking a refund.

I emailed "the supposedly" customer service email, which is studentservices@7sagestudentservices.com

but have not heard back in over a month..

If a support representative or someone who'd be able to help me, please check the email from sofiam1*********. It'd be greatly supported!

Thank you.
