Whats up with that ?

i bought a DVD as a present for someone and had it shipped with DHL , now DHL is more expensive than other carriers but that was okay i was in a bit of hurry for that present
they gave me an Estimated Arrival as October 12, 2007
so i check Amazon Tracking and its says
October 11, 2007 XX:XX:00 AM KUWAIT KUWAIT Arrival Scan

funny thing ,, today DHL came to deliver it ( October 16 , 5 days after it got to Kuwait and 4 days late from estimate ) , not only late but they demanded 5 KD extra , for what ? they claim Bayan Fee and when i asked for a paper for that Bayan fee , at first they claim its the custom , and when i check the custom paper it says ? ” معفى من الرسوم ” aka Exempt , so i demand to know what is that extra 5 KD , he call someone on his mobile who claim its an extra tariff’s i tell them I’m not paying anything extra for the hell of it , its not on an official paper , its just DHL invoice that say 5kd Bayan Fee ,, i could print one at my house and say ;
20 KD Bayan Fee
40 KD Shamiya Fee
30 KD Jarah Fee

I already paid for the shipping , i’m not paying extra to get it to me ! what kind of concept these paper run on ? charge and if you can charge more ?
