DHL is the worst

I ordered a dress from China, I paid an extra R1000 so that it could be shipped with DHL. The package got to South Africa in about 2 weeks. So I waited patiently for it to be delivered. After not getting any updates from DHL, I phoned them. Apparently the package was under declared, so I had to pay an amount of R1380 for it to be released. I paid the amount, only to wait again. So I kept phoning to find out when I will receive my package, and they said they're waiting for customs. Another week or so later I received a phone call, I have to pay a penalty of R900. I was furious, because I was told there won't be any more charges. But, I paid the amount that day. And waited another three weeks, I kept phoning asking when I'll receive my package, they again told me they're waiting for customs. Today I received another call, there's another amount to be paid by me. I'm absolutely furious. I will NEVER in my life use DHL again, they are the worst.
