The DPD delivery agent does not bring the parcels home
He left the packages outside the building floor (I'm going to a building on the 4th floor) and that has happened 5 times so far
And now I have bought a small PC and I have tracked it with the tracking number and it shows that it has already been delivered, even if it did not reach me. Therefore I will avoid DPD services from now on
