I’ve never purchased a modem from Comcast. Ever. But every now and then they seem to add “modem fee” to my bill. This has happened probably 4-5 times in the last 12 years or so. I have to call and have them remove it, then look back at old bills to see which ones also need the fee removed. I can’t help but think they actually do this on purpose. Like they run some query to see who has service but isn’t being charged for a modem, and just add the fee to all those accounts “by accident” hoping you won’t notice.
