Can't purchase XFi

I am trying to purchase one Xfinity WiFi Extender XFi for $119. The product page loads, but every time I click Buy I receive the purchase error page. I have tried multiple browsers while signed in as the Primary user. My local Xfinity Store says they cannot sell it and phone support incorrectly says the device does not exist. Can a Digital Care Team member manually process the order or determine why my account cannot complete the purchase? Please contact me through my email on record. I'd really like to solve this problem! Thank you.
