On the subject of DPD, last weekend I had an email and a text telling me my parcel - a new printer - was being delivered that day.
Later on, I was cleaning my car - which was parked outside my neighbours house - when a DPD van pulled up. The driver, who obviously didn't see me, got out, ran across the road and slipped a note through my front door, ran back and was about to get in the van when I asked if I could help. He replied that he'd tried to deliver a parcel but no-one was in. I pointed out that he didn't have a parcel with him and not only that, I live at the house and whilst I wasn't 'in' he didn't try to deliver anything other than a 'While you were out' note. He looked suitably ashamed and brought my parcel.
DPD should really say in their texts and email "We'll deliver your parcel today if the lazy ba$tard we employ to do the job can be bothered to take it out of the van"
