FlySafair online purchase frustration - Zero accountability

Made a booking for a flight from PLZ to JNB on the FSA app using my company issued credit card. The message came back that the transaction had failed. I went back to try a second time and the same result. Company accountant called to ask whu I had paid twice for the same flight. Received an email from FSA to inform me my booking still has to be paid! I spent a total of an hour between the bank's call centre and FSA call centre to no avail. The FSA payment "facilitator" had rpoblems and no one can give me a time line of when the money would be returned. I cannot re-book, or pay the outstanding, before the faulty payment had been credited. Why does it take milli seconds to debit the card, but the standard time frame for a refund is quoted as 5 - 7 days? This is costing me money, disrupting my bussines and makes my company suspicious of me!! For what?
