Never again will I use Mango or SAA

I went on a short holiday to Cape Town this weekend. The flights where booked on Mango. The flight there was fine. No issues. The flight back was delayed. We where to land in Durban at 7 and only ended up landing at 11. When we went to the check in counter the lady said that we where allowed to use the SAA lounge, I presumed because of the delay. We had a few hours to kill so I decided to go to the lounge. When I arrived I was met by the lady at the front desk and she said that we are not allowed to use the lounge. I told her that we where advised that we can use the lounge and she looked at me like I was lying and refused to listen to me. I made her phone the check in counter and they confirmed that they did tell me that I could use the lounge. She then took off with the lady at the check in counter and put the phone down. She then came back to me and told me that I am still not allowed entrance even though they messed up. I asked to speak to her manager and she said that the manager left. I asked to speak to her supervisor and she said she was her own supervisor. <br> <br> They seriously need to learn about customer service. I will now avoid SAA and Mango as much as I can.
