NO Attempted Delivery... what now?

Highly upset with DHL's "Don't care" attitude. According to my parcel tracking there has been an attempted delivery on 13/07/2021 but this itself is ******* as I am home all day every day, and waiting for a call to arrange excess payment as it is an international package.

I phoned this morning for an update and all the agent could tell me is that there was an attempted delivery and my parcel was handed over to the South African Postal Office and it is now my responsibility to sort this out. I have asked her to explain why the update states "Attempted delivery" when clearly there was absolutely no attempt, and she could not answer me. Parcels being sent to the South African Postal Office basically means I will never get my parcel.

What are you going to do? This is your mess up! Pathetic!
