Useless at customer service

I ordered a package from US and paid for premier shipping with UPS, cost me R500, on wednesday last week, it was stopped by Customs, on Friday last week UPS woke up and let me know they need documents from me which I sent within an hour, a week, 4 emails and 2 phonecalls later and I have still not had a response or even an acknowledgement that they received the email, UPS south Africa, way to shine the torch, you are an embarrasment to UPS, customer service is non exixtent
