Unprofessional and less than competent handling of my Item

Appalling service all around - I had ordered a small packaged from the USA. when it arrived, the description was unclear. I was called by FedEx and i gave the correct description. by the description, the harmonizing code is very easy and clear. somehow FedEx decided to ignore it and guess the contents and apply the highest tariff possible when this item gets duty free. I get a huge bill, i query it, after 48 hours i query again because this is urgent. i find out the staff sent it to the totally wrong section. it seemingly goes to the correct section. I fill a ton of forms and now I'm told i must wait for customs to refund FedEx. what kind of unprofessional entity is FedEx. this is not my problem. I want my package and i want to be charged the lower amount which i received via email and accepted. Why is FedEx making their issues, my issues? Their refund from Customs is their business by their own making. I want my package and i want it soon! this is unprofessional.
