Thanks for the update there, good source of info that.
I think it’s a given that the “serial number” that Cerberus quote to us is a different beast from the actual ONT serial number (as shown in your obscured screenshot). But they must have a record of the actual ONT serial number too.
Presumably your actual ONT serial number matches what you see from the ISP screenshot though?
Edit - I’ve had my ONT swapped out, presumably the BTW/Openreach records must be updated to reflect the change......hmmmmm. Wonders...
