Again, they are sending me to Apple. Seems like DPD won’t respond at all

That's ridiculous, they've got you running around In circles.

It's now come to the point of this. As per DPD's message below, forward It to Apple and ask them to explain why they're not willing to accept responsibility, when DPD clearly states that they should.

This is what DPD states
The parcel is insured through them for loss or damage.

Again I am being told to contact local authorities and they said carrier has not admitted loss of parcel so they can not provide insurance. They said we have checked all parties and there is no loss so Apple is not able to accept liability for your parcel
