Is this *****

Hi

I have been ordering my goods overseas for a while now and I have NEVER had to pay a customs fee so now all of a sudden there's a fee I have to pay. my question is WHY OPEN MY PACKAGE IF YOU GONNA TURN AROUND AND CHARGE ME????? who in their right mind comes up with these fees? R123 like for what? it cost you R123 to open my pakage? maybe its me who dosn't understand this whole thing and i would like some clarity because really this is ridiclous
