Airlink is the worst airline

Well basically what happened was I booked 3 tickets for me, my sister and her child. We then called in to find out if we could bring the child along as the baby had no birth certificate since home affairs had been closed because of the covid 19 situation. We were asked to bring for proof that the baby was hers, so we had the father's Certified ID copy, and the baby's birth record and an affidavit if I remember correctly. I booked online, and checked in online but when I got to OR Tambo, I just went straight to the airlink booth to make sure we were all going to be granted safe passage with no hustles to get to the plane. So there I met a kind lady, I honestly was taking down names as we were in a rush to get confirmation about the child so we could get on with our trip to Durban. The lady offered to help out because we had all the papers they required especially the birth records. She then asked us to call the father for confirmation and we did a video call in front of her. All this was happening while time was getting wasted on our side.

Afterwards the lady sitting next to the lady who was assisting us then whispered to the lady who was assisting and then the next thing we were told we couldn't board. Fair is fair, to avoid conflict and wasting time, I then asked for my refund since they had inconvenienced me to travel all the way to the airport and back from Northgate. We were sent to another booth were we spoke to a man who promised to assist us took down our information and nothing happened till this very day. Now they basically ignoring my emails and refuse to pay me back my money. Worst airline ever, don't bother going for it, biggest ****ers at the airport
