Received EMail - Your home WiFi assessment is complete - Get Free xFi pods link is broken

I received a WiFi assessment email from Xfinity since I am an Advantage customer and it said. 

You can improve your home WiFi coverage
with xFi Pods.

They're included with your
xFi Advantage service at no extra cost.

Your Home WiFi Assessment is complete.
Our advanced algorithm analyzed your use of
WiFi in your home. Our results show that your coverage will benefit from a few xFi Pods.
Three xFi Pods are available to you at no extra
cost as part of your xFi Advantage service.

 

But the link included is not working.  How do I go about getting these xFi pods on my promotion for free?
