Deleted duplicate listing, lost all reviews

Google sent me an email saying my business was marked as a duplicate, and it wouldn't show up in search unless I resolved it. So I went and deleted the duplicate listing, after making sure the info in the original, verified listing was correct.

HOWEVER, it turns out that all the glowing Google reviews I've gotten lately had been associated with the now-deleted duplicate - and I've come to really depend on those reviews to drive business.

How can I get that listing back and/or merge its reviews with the actual listing?
