Dhl are class A level idiots in Pakistan,
I have lost haltech ecus, lots of german car parts due to this. And then our lovely customs officers are illiterate sifarishi jackasses too.
They literally said to my face that a set of shims for a bmw diff cannot be 1 euro a piece as they are genuine bmw parts.
I showed them the catalog price which was met with, we in customs believe that consignee and recipient both are lying at any time.
Dont know about now, but i dont have high hopes that they hire educated people now.
What you can do is to contact DHL and stop them dealing customs on your behalf. You will then have to deal with them youself. i dont know if a dry port transfer is possible with DHL but its possible with ems
