No, but a small consolation is sometimes it's a temporary loss and they reattach to your listing.
One thing the help doc does not mention that I asked to have added was that sometimes a dupe can crop up and steal your reviews. Have you searched maps by phone and then by name and city to try to find any dupes to see if they have your reviews?

Ours did come back. I know this was a while ago, but just wanted to report, bc this just happened to someone else i know with a lot of reviews.
I'll try doing the map search you suggested Linda. UPDATE: No dupes found. Just all about 100 reviews gone.
I've noticed on the Google user forums that one thing that may trigger a wipeout of reviews is having a lot more than everyone else. This is definitely the situation in my friends' case. They have (had) over 100 reviews and are now down to 1. I think the closest competitor had 10. No trickery going on, though. They have a ton of clients and have done a good job soliciting feedback.
