Repeatedly dpd writes that the packages have been delivered, but it is not correct. Even today I was at home all day, when someone rings the doorbell this is recorded, i.e. "Overhearing" is not possible and still there is no package. It has often happened that it comes the next day or can be found somewhere in the neighborhood. Sometimes it just lies in the garden, thrown in, regardless of whether it rains or not - that is a huge mess and I have repeatedly criticized it - without any reaction from dpd. this is NOT a service, this is outrageous!
