BANK EMPLOYEE DOESN'T UNDERSTAND BUSINESS

Our client in Zimbabwe ordered our product. We sent him a PROFORMA INVOICE. He paid on proforma invoice, Nedbank received the US Dollars for our account. Nedbank e-mailed us asking for the Invoice. So I sent them the Final Invoice. Nedbank emailed us back and says the Invoice doesn't match the reference. So I sent them a copy of the proforma invoice. Nedbank emailed us back and said they cannot pay out on two different invoices. I tell them it's not two different invoices, It's a proforma invoice and final invoice. They email back and ask which invoice they must use. There is only one invoice. For one amount. They are refusing to release the payment. Incoming USD390,00 CBZ BANK LIMITED detection number ***
