Such errors on Google's part are very common. I worked for a Yellow Pages company that provides data to G and we used to get complaints from listing owners for supplying bad data, but the investigations always showed that the error lies in the additional crawling of web data. In my current assignment at a bank, a few dozen ATM listings contained the URL of a competitor bank and substantial amounts of "related" and "nearby" data for the competitor's ATMs. This required phone calls to Google Maps in Sydney and the solution was for us to delete all our entries and to resubmit.
So, I suggest that you are seeing a fairly common problem and the other business is probably unaware of this.
