Misappropriation of funds from account

I booked a ticket for my niece for this weekend and SAA deducted money from my account twice. I have been calling them repeatedly from this weekend and although they confirmed that there was a double deduction, they each claim that the previous agent didn't do the relevant work to refund me. <br> <br> Bearing in mind that you have to hold on for almost an hour each call, I am starting to believe that this is a gimmick on the part of SAA in the hope that customers will get so frustrated that they will abandon their claim and SAA may be able to once again be able to drag themselves out of bankruptcy. <br> <br> SAA you are a bunch of *******. I would like my money back immediately for the second amount that you ********ly deducted.
