Cablecard activation issues.....

https://www.xfinity.com/support/articles/pair-activate-cablecard. The only problem? The site it refers you to https://cablecardactivation.xsp.comcast.net/ DOES NOT WORK. From what I can tell in the forums, it hasn't worked for a while. I also found out from nearly every one of the 6 people I talked to, that they don't know about cablecards and that there are few people in the company who do. I finally resorted to a chat session while I was waiting for another "expert" on the phone and at least that person tried to help and did activate it. I've been a customer since 2007 and I cannot express in words the frustration of dealing with people who don't know what you offer. Even several days after I told each and every one to tell IT that the website wasn't working, it's still out. I really am happy with the reliability of the service, but things like this make me question if I should stay with you considering Verizon is into my house already for phone service and its just a flip of a switch to change. Please get back to me, and PLEASE for those who use cablecards, put useful information on you support pages or don't put anything up at all.
