Has Anyone Had Their Entire Website Stolen and Duplicated?

Today discovered that someone copied my entire website word for word, including the design. They seem to have changed only the logo and some coloring, but oddly enough, they kept my phone number and only swapped out the email address in the footer. Seems like they copied but never launched. We are a local home service company and this has taken a toll on our SEO. Our SEO person noticed a drop in search rankings and traffic right around the time their copy went live. It’s frustrating because I’ve invested heavily in improving my site, and now someone else is riding on my efforts. Has this happened to anyone else? How did you handle it, and did it affect your site’s performance in search results? I’m exploring options like DMCA takedowns, reaching out to hosts, or even considering legal action if it comes to that. There is no guarantee they won’t do it again so I’m thinking involving a lawyer would be a good idea. Any tips or personal experiences would be appreciated.
