Or don't have a landline or ex-directory. Voting register (electoral register) will be your best bet. or if anyone knows them.They arent on 192 so i can only assume they are relatively new. Its just so frustrating! The prices of the ex council houses has gone through the roof so its a decent area for schools, transport and local facilities. Dont know where the council found this family but they should do more to support residents when they put in problem neighbours!
Council /housing doesn't really take any notice of who people are. my next-door neighbour is all noise intolerant and doesn't like people and is aggressive but they put her in a little close of old and disabled people even though she isn't herself disabled physically
