Welcome to the Q&A Forum

Hi Jaco, It sounds to me like you may be dealing with duplicate listings, if there is no place to enter the postcard code you received. If you do a phone number lookup at maps.google.com, to do you see more than one entry for the business in question? Look up any previous phone numbers you know of, too, and you can also look up the exact address and see what comes up. If you can't figure this out, I highly recommend that you do start at thread at the Google and Your Business Forum (http://productforums.google.com/forum/#!forum/business) where you can get direct technical help from a Google employee or TC on this. They may well recommend that you start a troubleshooter ticket. Sounds to me like you may have run into either a complex problem with duplicates...though there is a slight chance you've encountered a bug. Google's staff and volunteers will have the ability to verify this by looking under the hood, if you can get a response to your thread.

Is there any identifiable information here? First a quick check to see if there's a privacy issue -- if you click on these URLs is there any info in the URL giving away the email address, name, etc of people in the signup form? Right now there's not a way to hide it on a report, but you might see if there's a way to just exclude that via a robots.txt just to save your crawl budget and make sure that it isn't a problem with the search engines.

On the Overview page in the Crawl Diagnostics box, click on Duplicate Page Title on the Y axis. It will send you to a page that lists the duplicate page titles.
