I've been trying to add my modem that I have to my Xfinity account. However, it seems like someone in Washington has the exact same model and MAC address listed as their active modem on their account (I live in California). I've called about 5-6 times trying to get this issue resolved, but have not gotten anywhere. I purchased my modem new from BestBuy less than 3 years ago, and it has never left my possession. The other party added it to their account 2 months ago.
It's been extrememly frustrating trying to resolve this issue. Each time I call, the representative says that they can't do anything because it is the active modem. They keep trying to get in contact with the other party. The first time they said an unauthroized user answered the phone. All subsequent attempts have gone to voicemail. This definitely sounds fraudulent to me.
I've asked a Comcast employee to help you. You should expect a reply in this thread.
