Process for Taking Down a Fake Website Posing as My Business

I discovered a fake website posing as my business, and based on a WHOIS lookup, it’s registered with Namecheap. I’m concerned that reaching out to the abuse phone and email listed might be futile, as I’ve heard mixed things about Namecheap. Should I report this directly to Google, or is there a better approach to getting this site taken down? Any advice on the steps I should take would be greatly appreciated.
