Rosemary - I am sorry to read of the issues you are facing.
You can
apply by post for copies of paperwork submitted or obtained during the registration process
However before doing so I would recommend submitting the
Contact us form to establish what paperwork we actually hold and specifically the survey report you refer to. The support team can then check our files and respond
We will only usually have such a report if we requested one but worth checking what we have first before trying to apply by post directly
The wider issues and history of contact with your neighbour(s) and others isn't something we can advise on or resolve. We would always recommend seeking legal advice in such cases to consider what rights/options in law you may have
There are also online forums such as Garden Law and Money Saving Expert where such matters are often aired and shared and others often offer comments based on their own experiences/understanding. However as you and your property/neighbours are unique it is invariably specific legal advice that's the best option
