Hi Jason
I've never had this problem yet (touch wood) but what I find works is verifying the actual business via phone or postcard, which you have done, linking the web URL in the 'Contact Us' section and then creating a Google+ button on your webpage which links to the URL that you have entered.
E.g.
http:www.russkellfurniture.co.uk
https://plus.google.com/106174762290348981656
Sometimes it takes a couple of days for Google to recognise that they are linked, but this is the way I usually find works.
If you're still struggling in a couple of days time I suggest you try https://support.google.com/places/contact/c2c_places (they are online from 2pm UK time). I've spoke to these guys a couple of times regarding issues with Google Places and Local accounts and they always sort the problem for me.
Let me know if you're still having trouble!
