Royal Mail 24 hour tracked service? Well, it's not 24 hour guaranteed - it could take any length of time - and it's not tracked properly either. It's scanned into and out of delivery offices but that's all, so if your item goes to the wrong office like mine has, and doesn't get scanned into the right one, then they don't actually have a clue where it is! Someone's pocket maybe? Three different stories from three different members of staff. A 'sorry' isn't quite good enough when my item has been in transit for nearly 72 hours to make its way 15 minutes down the road, and I'm £122 out of pocket. Diabolical, appalling service. DO NOT USE.
