"free changes" no way

"Free changes is a ****

I paid dear for a flight and wanted to postpone it, I first checkd and found a flight a few days later with the same cost. When I rebooked my initial flight, lo and behold the system gave me only one option for a cool R1-5- more! but yes with no "fee"

The rebooking system is design so that you have NO CLUE what flight options you will be given, and you are let out to pricing that only the airline knows."
