WORST SERVICE FROM FEDEX

I was sent a gift package from the US through a ware house shopping/delivery company. The shipment was shipped through FedEx. Getting to Cape Town it took the FedEx representative almost 2 weeks to attend to my shipment, at first she kept telling me to send the commercial invoice for the shippment which I did for a couple of times only to find out after one week to almost two weeks that she has problem with her email. After she managed to attend to me it took her another 48 hours to clear the shipment and then I was sent a custom invoice fee to be paid. I quickly went to pay it hoping that it will be cleared and delivered the following day. Only to find out that it wasn’t cleared nor delivered as I was told the shipment has been sent to delivery department to deliver it. They refused to inform me what the problem is for not delivering the package until I sent serveral emails then they finally rep**** after 24hours, to tell me the package wasn’t cleared and that it was stopped by post custom border control unit asking for price list/catalogue of goods that wasn’t bought. I sent emails no replies until I called this morning then the representative told me they will open my package to check if it’s new or used. I don’t understand why and when FedEx have the right to check people’s packages. I don’t have any problem with them checking the package, they should either deliver the package or they return it back if they don’t want to deliver it and please refund me my money paid for custom fee because this attitude of the reps is looking very fishy and disappointing.
