The next day I called them since the chat was busy, attempting to DNA rep said that I have to check if my neighbor received my package or contact the courier and call DPD support to get his number. They can't do anything before 3-4 days after that, they can open an investigation or help me, ofc I need to contact the courier first. What should I say when contacting them by chat?

When I checked the signature on the DPD site letters don't match any of my family members with me included.

You've stated to check with the neighbour "or" contact the courier.

Is It either or both?

I need to check neighbors if I don't find anything then contact the courier, rep insisted on contact with DPD. I think both.

It's not your responsibility to contact the carrier.

The company does It through an Investigation.
