Incorrect Google+ Link
Please search "Fantastic Sams" The google plus profile that is showing is both unverified and unauthorized (https://plus.google.com/+FantasticSamsSalons) . They are using a url this is very similar (www.fantastic-sams.com)
Re: Incorrect Google+ Link
Thanks for writing
But searching for "Fantastic Sams" we get not a Knowledge graph of a GoogleMyBusiness listing but a Wikipedia based Knowledge graph "Fantastic Sams" like searching for "Google" or "Hugo Boss" or "Microsoft"
I believe therefore we can't much help you about this here.
The other point I like to express my doubt are the both G+ pages you refer too.
Neither of both seem (IMHO though) G+ pages of the brand "Fantastic Sams" but being G+ brand pages of a single location.
I recommend you to post your concern about the shown Knowledge graph "Fantastic Sams" via the link "Feedback" below the Knowledge graph.
