After a recent success through the Small Claims Court process I discovered that sending mail Recorded Delivery, does not necessarily mean that the addressee has to accept delivery. The dealer in question had refused to sign for delivery. This explains why I did not get a single reply to any of my letters. Royal Mail had to open all my correspondence to find my address and then return the letters which obviously caused some delay before I became aware the returned letters had not been read. It was only when the dealer received notification from the Court that there was any response. Fortunately my claim was successful and my money refunded in full.
