I did get a reply to the letter below -- in which they politely told me to bugger off -- but the fascinating thing about the letter concerned -- I am almost inclined to scan it in -- is something I have noted before:
Far from there being a return address on it, there was NO ADDRESS OF ANY KIND on it.
They REALLY hate talking to their customers!
Just to upset that applecart a little, the address I used for them -- which works -- is:
PO Box 306
