Fedex is DISGUSTING

I always use DHL for my international shipments with NO issue. But for the first time I used Fedex because MyUs.com was promoting them. Let me tell you. The service is DISGUSTING. First they send you an email asking for my ID Number and they give you 3 days to respond or they will return your item. And yet they give you no option on where to send it. Their customer care line just rings with nobody answering it. Their CHATBOT is so generic its like talking to a brick wall. Finally when they acknowledged the ID then the problems started. They have charged me R2700 import duties on an item I bought for R3400. When I queried this they told me to send them the invoice to prove this amount. I sent them the invoice and waited. Then their driver rocks up with the delivery but I must pay him R2700 first! I refused. So he left with the item. Finally after multiple calls, emails, Fedex responds with this beauty. I must pay them R700 to adjust the import duty fees!!!!!! Now I have 3 options. Pay R2700 for an item I paid R3400 for. Return the item to MyUs or discard it. So there is no win for me. Fedex has offered me a LOSE, LOSE or LOSE scenario and let me tell you. They couldn't give 2 damns which of the 3 options I choose!
