I have used recorded signed for for some time but recently it really has gone down hill.
I have packages just posted thru my door that are recorded and have had a pretty high percentage of items I send not arrive.
I have spoken to a couple of postmen and apparently the sheets 'they should' get signed arent even asked for when they get back to depot.
One Postman even said he has them all the sheets in his bedroom!
This would account for the lack of tracking info for a high number or items on the Royal Mail website.
Having spoken to RM Customer services they now simply class items that have no tracking info as 'lost' and to put in a claim.
