Illegal additional charges
So DHL gave me an invoice full of errors, they calculated the freight into the value of the goods thus inflating the duties and VAT, they also charged me a penalty fee to revise and correct the invoice and duties without warning the client. 
I now have an invoice almost R1500 more than the one in dispute. 
They also did not tell the client that they will charge a R900 fee for amending the invoice. This is criminal at best. I will contact SARS tomorrow to blow the whistle on this malpractice.
