SAA ****, MISSED FLIGHT BECAUSE HE GAVE BOARDING PASS AND DIDN'T CHECK BAG IN

DON'T EVER EVER EVER USE THIS HORRIBLE AIRLINES, THEY HAVE A ****, THEY GIVE YOU BOARDING PASS THEN REFUSE TO CHECK IN BAG, TELLING YOU TO TAKE A BIG BAG TO GO THROUGH SECURITY, WHEN YOU GET THERE THEY REFUSE TO LET YOU THROUGH, SENDING YOU BACK TO THE PERSON WHO GAVE YOU THE BOARDING PASS ASKING WHY HE DIDN'T CHECK YOUR BAG IN.He then says he can't do anything, this is after you run back from security check through to boarding gate. The ladies there say he must escort us if he did not check the bag, he refuses to come and just sits there. We go back again and he says we must buy another ticket to check the bag in..... THIS CAUSED US TO MISS YOUR FLIGHT. THE SAME GUY SAYS HE CAN'T DO ANYTHING, GO BUY ANOTHER TICKET. At TICKET SALES THEY CHARGE YOU FOR NO SHOW, EVEN THOUGH YOU WENT THROUGH AND IT'S NOT YOUR FAULT, HE DIDN'T CHECK THE BAG IN... THEN YOU MISS YOUR NEXT FLIGHT AND THEY SAY THEY CAN'T DO ANYTHING ABOUT IT EVEN THOU IT IS THEIR FAULT!!!!!!!!!! We even saw the air hostess for that flight there and she said they could send the bag through and they will take it and keep at the back but the security refused. Yet on the 2nd bought flight after checking in the bag, on boarding the security asked if I wanted to give my cabin bag in and collect in baggage when I landed. YET THEY COULDN'T DO THIS FOR THE FIRST FLIGHT AFTER REFUSING TO CHECK IN MY BAG. I HAD TO BUY 2 NEW TICKETS AT RIDICULOUS PRICES, THEY DIDN'T EVEN LOOK AT THE DIFFERENCE BETWEEN THE TWO EVEN THOU IT WAS NOT OUR FAULT. We told them we missed flight because of the guy giving boarding pass and not checking our bag in but I think they know the **** and they are all in on it. AND I SPECIFICALLY USED SAA FOR THE CHECKING IN BAG PRICE INCLUDED. PLEASE COME FORWARD TO EXPOSE SAA IF YOU'VE HAD SIMILAR ISSUES, PUT IT ON EVERY SOCIAL MEDIA TO MAKE EVERYONE AWARE
