Flight missed due to terrible service and VERY poor upgrades!!!!!!

<p>I was scheduled to fly from Johannesburg to Windhoek on Saturday 2nd of July at 13;15. When I got to passport control, the lines were incredibly long!!!! Hidden behind a pillar I saw a message from ACSA saying that they are busy with biometric upgrades and this may cause delays...but if you are about to miss your flight you should inform an official! And of course there were NO OFFICIAL TO BE SEEN!!!!!! When I tried to skip the line to get to the front, because my boarding gate was about to close, I was instructed to get back into the line and the officials at the gate refused to help me!! After about another 10min, someone infront of the line told me to go infront of him (very thankful!), after which I ran to my boarding gate which obviously already closed....I then had to book another ticket beacause SAA would not re-emburse me! </p> <p>I find this highly unacceptable and extremely inconvenient, seeing as there was only 1 counter open at passport control gates to begin with!!!</p> <p>Definitely going to open a formal case!</p>
