They probably did put a fax no in as I rang today and after 15 mins of trying got through to be told to ring 01379 649499 , which i did and after another 10mins a nice lady took my name and address and model and promised me the case would be in the mail.
I believe that Sonys offices in the UK are in Diss as thats where I sent my claim on the VAT refund for my 650
I also received mail from them with the return of my receipt etc that I had sent them and a note that the refund would soom be paid to my account
all in all im pretty happy with Sony at the moment
