Absolutely useless! Turned up at the address when someone was at home, said no one was at home. Didn’t leave or contact the concierge. Came back the next day, again, someone in the flat and the concierge waiting in the front of the building as I tracked the driver. App said 15 mins to arrival warned the concierge who said he saw a dpd van pull up take a photo of the front of the building and drove past. I then received the photo saying sorry we missed you, you must have been out. Outrageous service and will never use them again, nor will I use the vendor if they continue with DPD.
