Good Review Bombing?

Our business has been recently flooded with 5-star Google maps reviews…for a different business.

We have a small restaurant, actively manage our Google site and our own website. Recently, I noticed a review for a garage door company pop up on our feed. I reported it as off topic and moved on.

Since then, we’ve been getting 2-3 a day. All five star, from people with no previous reviews, all generic for a garage door installer.

I’ve reported all of them to Google, however now Google has starting to decline to remove them (does not violate our rules), and more are coming in. I don’t know how to address it, we’ve never paid for reviews or SEO of any kind.

Anyone else experience this, or know what to do to get Google to remove obviously wrong reviews?
