Can't complain, no service to complain about

My parcel took 2 days to be in South Africa. It went for custom clearance and the moment I received the invoice I paid it. Ever since it has not yet been moved. I spoke to a consultant yesterday who said that he would tell them to move the package yesterday, today the exact same story. The last update I had was on the 15th at 13:20, informing me that the shipping was paid for. I know it was paid for because it made its way from China to South Africa in 2 days. I have sent an email to: '***' on which I am STILL WAITING FOR A RESPONSE. This email was sent on the 15th at 17:26. As an international company, I thought that you would have adapted to the international standard of customer service, but I was mistaken......This is South Africa
