Here's the link: https://plus.google.com/117607670399105979743/about?partnerid=lolnd - that's a local page, isn't it?
If i understand the question correctly,
You can delete the G+ Local page but not the entire account by simply logging into your Google+ account --> Profile --> Pages tab (in the left sidebar) --> find your page and click the dropdown arrrow, select "Settings" --> scroll to the bottom, and select delete this page/account --> confirm the deletion and you should be finished.
I saw something to indicate that SABs are not able to be edited in GMM now. I will report back.Odd, I can't find the listing in Map Maker and it's not allowing me to access the Report a Problem feature for the listing. I wonder if it's already been flagged.
First of all, remove it from the Places Account which I think you have already completed.
I was thinking the best bet would be to report it as "Place Does Not Exist or is Private" via Report a Problem right from the listing. Or possibly reporting as closed...
Andrew has really good insight into matters like this. Hopefully he will stop by.
Regarding the UPS address, if you're worried just change the address in the dashboard if you're able. Since its a SAB the address is hidden and won't be exposed beyond Google.
