No baggage trolleys at international arrivals

Arriving at OR Tambo on Sunday 10th January at midday there were lots of passengers arriving but no trolleys. I asked a group of officials where the trolleys were located and was told opposite baggage aisle no.2<br> So I went back there and all the trolleys were gone (as I expected)<br> Returning to my luggage another official asked if I had managed to sort my problem out. No I said since it was obvious I still didn't have a trolley.<br> Doesn't ACSA know that trolleys need to be collected at pickup points and returned to arrivals?<br> I thought ASCA wasn't another state run fiasco but maybe I'm wrong.
