The survey network note ( SNN) is along the lines of ‘ pre built to the curtilage, no dig’ , this should mean that new duct was provided to the boundary of the footpath and your garden or house ( the curtilage ) and either a toby box or a duct marker provided at that point , ‘no dig’ , I’m not familiar with that term , does your property front directly onto the footpath ( no front garden ) ? .
This duct work is normally done by contractors, if they have messed up , and because it’s covered by the reinstatement, you only find out when OR attempt to cable from the jointbox with the CBT in it , to the Toby box or duct marker, it should be the case of getting the contractor back on site to sort out any blockages etc …..in one respect you have been unlucky that the contractor didn’t leave a serviceable duct when that’s what they were contracted and paid to do , this first delay was not OR’s fault they would expect brand new duct to be blockage free.
TBH , I can’t really understand the lengthy delay , once the stoppage is discovered it shouldn’t take as long as it has , the other error is if the OR tech that couldn’t cable this duct closed the job off as done when it should have been ‘furthered incomplete’ to indicate that a problem was encountered.
Unfortunately I can’t offer any advice in speeding up resolution, you need to keep on at BT/EE to get OR to expedite any work required, including getting the contractor back .
