DPD UK review: Lack of delivery : 1550 4665 234 520 9

I ordered an item from Dimplex. Delivery was scheduled for 13 July 26. I received a text from DPD to say that the driver is 3 minutes away. He didn't arrive and got a photo of the backend of factory or something. I send the Customer Services my W3W and requested the delivery to be put on priority.
14 July. I get a text from DPD that the drive is very close - a few minutes away. Again - no show. The delivery had not been put on priority as I instructed.
I have now paid DPD £4.99 to have my parcel delivered.
This means that DPD have been paid twice for this delivery.
Once by Dimplex.
Once by me.
Either the route planning is not great or your AI engine is telling you lies.
Having working in Delivery Logistics for 6 years, this is a run around.
I ship often to South Africa. If DPD cannot deliver to me, a short distance from Hinkley, how will they cope with delivery on my international deliveries?
