SAA
Incorrect Resevation Date

So I books a return flight with SAA to East London using a friends credit card. We're both doing the booking and we double and tripple check that all is ok. We paid. When the email confirmation cones through, return date is incorrect. Instead of 30 June, its 05 July. Now I have to pay an extra R1500 to change a booking I know was captured correctly. I am sooo not impressed and very disappointed in our carrier. Will I use them again, I doubt.
