Terrible and impossible.

Terrible and impossible.
Parcels have been sent with DPD 3 times in the last 2 weeks. No one came twice even though I was at home and my parcels were brought directly to a pick-up shop, where I had to pick them up myself. Today my package was simply put in front of the front door. Again the parquet floor didn't ring. I was at home and found the package after the notification. Find this way impossible. If the package gets away like that, you are left with the costs.
Complaints are useless, nothing changes.
