Trouble with address when switching from Business to Residential

I’ve run into a blocker switching from Business to Residential. After calling business support, all I need to do is activate residential service through Xfinity, then sign the voluntary disconnect form they sent me to turn off business service.

My address is blocked for use on Xfinity. It says “this looks like a business address” online when I search it. After calling Xfinity support, they even opened a ticket to fix this and add my address to residential, however the ticket came back saying residential service wasn’t available at my address. (which is a definite mistake, as it’s a house and currently has Comcast business service)

I’m not sure what to do next. Please help.

Thank you
