Ordered business cards to be delivered by DPD to my address at a block of flats. I received a text saying that my order had been delivered and was signed by me but I never received anything - I received no phone call nor heard my buzzer go off. They included a photo "proof" which was seemed to be a blurry photo of the delivery driver's hand. So I got the company to re-deliver another set of business cards to me. Turns out DPD had left the package outside the front door of the block on top of the buzzer which could have been taken by anyone who saw it.
Second time around, it was to be delivered by DPD again and, again, they didn't even bother to ring the buzzer or my mobile. Luckily this time they thought to leave the package at a local pickup point.
DPD is literally the worst carrier in the country.
