SAA
Have been charged for R3509 instead of R930

Made a booking (YG73HD) the amount that I have been told it will cost me was R930, the next day SAA charged me for R3509, when I called and spoke with the supervizer all he can say is sorry we did a mistake and he refuse to refund me.
I need to be refunded for R2579 which is the difference.
My number is 082 6501200
I will not accept anything else but a refund.
Thank you
Tal
