DHL shocking

Package sent to Germany 6 November 2017. We adhered to all requests for documents and DHL delayed so long that customs period in Germany expired and package returned to SA. Now I have to pay VAT to release my own goods which I already paid VAT on when I bought it and lose R4000 it cost me to send the package in the first place. DHL SA do not respond to mails and gives no feedback. Shocking service will never use them again
