Get a neighbour address that has it , next door if possible, and use that as evidence. Get 2 to 3 addresses around you and go back to your isp. They should have a process to fix
As you said just loking at your flat on the bt address checker, all the flats can order fttp, but you can only order adsl.. bummer. You need to get your isp to get the bt line db fixed.
