SHARP logistics should be renamed to SHARK logistics

I bought a LPG carburetor for my generator from China and was couriered through DPEX and handled by Sharp logistics in SA. The price of the Item was about R500 and then they send me a Customs and VAT invoice of R582!! How on earth can the duties be more than what I paid for the item?!? Went through the Customs documentation and found the my item is also duty FREE and the VAT on it was R94!These people then just added a "CLEARENCE FEE" of R460!?! Emailed them about it and got a reply that it's their "STANDARD FEE" for anything they handle for imports! This is **************** and a bunch of SHARKS! DO NOT use them!!!!
