Suspicious system glitch

I recently booked a return ticket on [URL Removed] with the intention of departing JNB on Friday 13 Feb, and returning on 17 Feb. On arriving at CPT airport for my return flight, I was told that my actual return flight was booked for 17 March. Interestingly, the check-in person let me know that this had happened to a couple of other people in the last few days. Which got me thinking - did Kulula purposely set up the return flight to a month later (in Feb and March there is no difference in the days of the week, so 17 Feb and 17 March fall on a Tuesday). I would never have skipped a month intentionally, so I suspect the system was set up to jump automatically a month ahead, and unless you checked that very carefully on booking, you would not have been aware. Be that as it may, Kulula may have made R1160 extra from me, but they will not ever make an extra cent from me. Not impressed!
