Wifi assessment done, cant order my 3 xfi pods

Hello,

 

I did receive the email "Your home WiFi assessment is complete." telling that "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 when I use the link provided in the email, I end up with an error "We're sorry.
Please call 1-800-Xfinity and one of our friendly and knowledgeable representatives can help."

But after over 1h over the phone with different service, noone can help me.

 

I have seen some users having the same issue.

After using the link from the email I land on a webpage "xFi Pod/3 Pack" with a link "Get Pods".

Then I have a screen looking up xfinity plan, checking price, checking availibility and finaly the error screen above.

 

How can I get the free pods I should be able to claim after the wifi assessment?
