its a long and complicated story involving a private arrangement of maintenance being changed to a payment thru the CSA ( as demanded by the PWC) then back to private arrangement (as dictated by the PWC when they got awarded less £ than she was getting originally) .. but the 'lady' dealing with the case is very aggressive on the phone , doesn't answer questions etc etc , replies to letters asking for clarification of payments without answering the request etc etc ... and she (or somebody from the CSA office) has taken to hand delivering letters to our address in the evenings...this has happened twice now , when someone pulls up outside at around 6pm and puts the letter through the door and drives off..
Is this some sort of abuse of the personal information they hold.. are they allowed to personally call at your house? and I am allowed to take their car registration details etc and complain?
