I am picking up mail from Baroness De Rothman addressed to my father. It says "I am surprised that you have still not used the cheque for £1,500.00 I sent you. I am worried about you!". She is apparently a clairvoyant and expert in telepathy. Evidently not a very good one. My father passed away in March. How do I stop this unwanted mail as there are now new occupants at that address?
