Can't place order on https://customer.xfinity.com/devices/equipment-update/

Hello, a month or three ago you guys started doing upgrades in my neighborhood and I got an email on October 7th saying that I'm eligible for a free modem upgrade to get the new speeds. I went through the little self checkout thing but never received a confirmation email of any kind nor did I receive a new modem. Then again on October 14th there was a text message from xfinity saying that I can upgrade my modem so I pressed 1 and it said it would ship it to the service address on my account and send a confirmation email with tracking information which also never arrived. I've tried clicking the banner at the top of the account page which takes me to https://customer.xfinity.com/devices/equipment-update/ to submit the order again but it just gives an error when I click submit saying to retry. 

Any help is appreciated, thanks.
