what tier of business internet do I have to have to get access to xfinitywifi hotspots?

Hi:

I'm a comast business internet customer with the package:

Deluxe 50 Pkg Business Internet

and have been active for a couple of months

according to http://www.xfinity.com/wifi/faqs.htm

I am an XFINITY customer, do I get free access?

XFINITY WiFi is available for no additional charge to XFINITY Internet and Comcast Business Internet customers who subscribe to one of the following:

Performance tier and above
Business Starter tier and above
If you are a new subscriber, you can begin using XFINITY WiFi right away, even before your XFINITY Internet service has been installed at home.

when I try to log into a xfinitywifi access point anywhere with my Comcast business Email and password (the same that I use to look at and pay my bill) I get an error message saying that (paraphrasing) "you're not subscribed to a valid tier of service and therefore don't have access to xfiniitywifi"

(business) Deluxe 50 is a higher/more expensive tier than (business) starter...so shouldn't I therefore have access to the xfinitywifi hotspots?

Can someone with Customer Service help me with my account so I can have access to these hotspots?

thanks,

David
