The lies that the service advisors tell

I booked a flight at Cape Town International Airport reservations and paid via a cheque card. The payment was successful but needless to say, the agent was having with the problems card machine/system and was requested to rather draw cash and make a cash payment, which I had done. The advisor said the transaction will be reversed for my card payment and the money should be returned into my account immediately. 5 days later, the money has still not been returned into my account and I really do not have intentions of donating to BA. I need to have my money back urgently, she **** and then she ran away. I am not happy at all.
