How do I get a site shutdown because of fraudulent activity

Hi Community,

I’m having no luck speaking to someone at Shopify, so I thought the hive mind might be able to help. I have a company that has a shopify site - https://grillwhiz.myshopify.com/pages/contact the address being used is one that I work for, and it has nothing to do with Grills as you can tell by the name.

How do I go about requesting the site to be shutdown? as I do not own the site and therefore cannot gain access to the Control Panel to do this.

Any assistance would be most welcomed.

Thanks in advance.
