Online parking booking fail

Tried to book long stay parking at King Shaka Airport for my mum online. A message came up on the screen saying I should call ***. I call it, some female answers and the minute I mention booking a parking there is radio silence. This happens twice. Give it some time and call again and another female answers-not sure if its the same one. Tell her I want to book parking and she says no its first come first served. I said look, I tried booking online and it told me to call this number so how does this work?! She then became rude and said no no no we do not make bookings here! And this is when I cut the call because I didn't want to continue a conversation with this absolutely rude person. ACSA get your information correct on the website and maybe arrange some customer relations training for your staff because that was simply pitiful. There was no need to be rude. Considering the terrible reviews I've seen about park & fly services I was hoping to get some peace of mind by booking directly through you and maybe saving some money. Guess not. One would think you are in cahoots with those ********* using the cars meant to be parked at a secure location.
