In the last 5 years, I have used Royal Mail's track & trace service about about 10 times, and for 6 of those times, they have either lost my items or been unable to provide a proof of delivery. Once it was for a cheque for £4,500 which took me 2 months and a lot of hassle to get issued again! The latest was quite a large parcel, with contents to the value of £150; this parcel has been 'lost', although it shows as being sat in the Warrington depot for 11 days now. I have struggled to communicate with Royal Mail, despite many attempts, finally resorting to 'TWITTER', which has produced a response at least. I have made a claim for my lost parcel, but the insurance only covers me up to £100, so I am down £50 and up a lot of stress and hassle. I WILL NEVER USE ROYAL MAIL AGAIN!
