Xfi pods

Upgraded to unlimited internet and a free assessment on my internet to get free xfi pods if they thought I needed them. I got an email that said I qualified for them. The link is not working and says it's unavailable for purchase. I called Xfinity and the representative told me that they could not ship them to me. Very disappointing seems like they are just looking to make an extra buck, and not meeting their end of the deal.
