DHL requesting unnessary permits

For the past 3 weeks i was told by DHL on a shipment hat I need an ITAC permit before they can release the shipment. Paid a few thousand for an Import/export license which was required before I could apply for an ITAC permit. Paid another few thouosand then to apply for the ITAC permit, only to be informed in writing by ITAC that a permit is NOT required for NEW motor vehicle parts. I just do not get any feedback from DHL on any of my emails. Who is going to refund me all the money I paid for permits which is not required. I also still have not received my imported goods. All import taxes/duties already paid 4 weeks ago.
