Always trouble with DPD! It is always the same as I see you - you are standing on the street (always the same 2 deliverers) take a break, and suddenly the e-mail - package arrives in the parcel shop the next day! What the people at DPD are paid for is a mystery to me. With all other deliverers z. B. DHL, GLS, UPS never had problems.
And I have already complained twice to DPD by phone - they are not interested at all!
