You are correct and that is wierd! Syndication from K/W, but brokered by Cobblestone???
Anyway, if you click on "report error", found on the right-hand side of the listing details, (over by share on facebook, etc.), this should pop-up another screen. On that screen drop-down the menu to "incorrect broker/agent," fill in your description and email, then submit. **NOTE** You have to choose (or not choose) to remove until this is resolved. Not to tell you how to do your business, but I would prefer to have the listing live, with the click-thru coming to my (your) site, instead of having no listing at all!
I pay a little money every month, to have all my listings "featured" AND the ability to claim and market my listings how I see fit. I hated having the brokerage picture, or any one else's picture on my listings! Hope all this helps and best of luck!
PS If you are "over K/W" and interested in a change, give me a shout! Sorry, had to recruit a little!
