I use DHL / UK Mail for business, for the past month their service has gone down the drain, totally useless, I am sending parcels on a 24 hour service, 4 working days passed since the parcel shipped out and still showing delayed, and on the other side they are keep loosing parcels.
Since UK Mail and DHL joined together you can't trust their service, to start they were very good, but after a while they have the worse service ever.
