BLG Comiting Customs ***** and blaming the customer.

Regarding BLG Johannesburg South Africa. They used the wrong HS codes and product descriptions on import documents and then blamed us for the mistake instead of correct the issue. They also charged us R32,000 for import duty despite our product being duty free. We brought this to there attention but they did nothing except threaten us with there legal department because we refuse to pay (We can't pay this invoice as it is customs ***** to declare the wrong product on import documents.). While they refuse to change the documents they have rang up R80,000 in Demurrage and Storage fees. More than the potential legal issue these shipments were 30days late and the invoices were MUCH higher than the quotation. We are letting our customers down and they are loosing business because of the 45 days the machines have been tied up.
