I've only used it 3 times in the last couple of years (including last week) and only 1 item out the 3 arrived! Worryingly for me the one I sent on the 13th Feb was my very 1st mobile cashback form for my daughters phone (worth £360 after 4 cashbacks) and it still isnt showing on the track & trace online facility (22nd). If you ring Royal Mail they tell you its not considered missing until after 15 days and not to bother ringing them again until that time has passed! Why pay the extra on top of 1st class to get proof of delivery when they can't even get the thing to the door! Anyone else have these sort of problems cos at the end of the day they will just say sorry and send me a book of stamps for my trouble if I'm lucky.
