SHIPMENTS BY DHL FROM GERMANY ARE EXCEPTIONALLY SLOW

I had 2 shipments by German companies and 1 Slovak shipment by them, all in Oct-Dec 2020 timeframe (from EU to US). The Slovak shipment was by air and completed within 5 days and accurately tracked (weighed 1.75k) and cost only 16 €. On the other hand, the 2 shipments by German companies were exceptionally poor, TOOK 45+ DAYS TO SHIP and minimally tracked and cost more than 30 € each. Both the German shipments were lighter than the Slovak shipment - and were SHIPPED BY SEA SHIPPING CONTAINER! DO NOT USE DHL FOR ANY GERMAN SHIPMENTS!
