Customer owned SB6121 modems listed as "LEASEDMODEM"
Today, I logged into https://customer.comcast.com/ to check my account status prior to paying my bill (as I usually do just to make sure that nothing has gotten screwed up with my account).

Prior to today, the modems were never classified as "LEASEDMODEM" (nor should they have been, since they are not owned by Comcast). Shown below is a screen shot of how they have always appeared on my account (prior to today):
What do I need to do (other than turning the matter over to the local FCC Franchise Authority -- as I had to do in the past for a similar situation with a residential Internet account) to get Comcast to stop claiming that my personally owned modems belong to Comcast?
