Refund course but unable to get any response

I have sent multiple emails to refund a course that I have purchased which has a 30-Day Money-Back Guarantee. What is the another best way to contact codewithmosh other than their contact form?

Thank you for your help in advance.

Email support@codewithmosh.com. That is the best / only way I know of.

Right @codewithmosh ?

If they do not respond you could try Teachable: support@teachable.com
