Incorrect billing details on invoice - cannot be corrected

We have been struggling multiple days now with clearance support agent Koketso Modikoe to get our business name, address and VAT number correct on pro forma invoice 034679. The correct details were provided very clearly multiple time and every time there is something incorrect or just seemingly from a different planet. Today's follow up after waiting a day without response I have been advised to pay first and then the issue can be corrected. There is no way that incorrectly addressed invoices can be paid.
