I've been suffering similar problems (see http://www.london-se1.co.uk/forum/read/1/119403
I'd almost given my special delivery package up for lost, but it eventually arrived a week late. When I signed for it I mentioned that I'd been waiting a while to which the chap replied "Well, that's the Royal Mail, isn't it?".
I also sent myself six letters between the 21st and the 28th. To date only three have arrived, taking an average of three days to get from SE1 to SE1 with a first-class stamp.
