The PENDING FNB problem

On the 04th of November I booked a flight ticket with Mango Airlines to fly on the 07th. I used my FNB credit card and I got the usual sms that the payment is reserved. On the 06th I realized that I did not receive my reservation number, Which was very strange, as I wanted to check in online and reserved my seat.

I then checked my credit card online Acc and saw that the amount is pending; which is the reason Mango never issued the ticket. This amount was still pending 7pm Friday 06th of Nov. I called FNB and told them about my problem ( call ref Rr*** ). The more I told the agent my app states the amount is pending the more he argues the amount when through. I told him to cancel it since it is still pending. He offered me a debit dispute form. I told him I need to fly tomorrow, he the advised I buy a new ticket. I bought a new ticket wit Safair.

This is my problem: the debit dispute form don’t talk about pending mistakes from FNB. And it does not talk about airlines. I need my money refunded please.
