COMPLAIN AGAINST FLYSAFAIR PERSONELL

I booked a return ticket for me and my sister and the gates in our boarding pass were different even though we're going to the same place. So I had to run around to make sure that everything is sorted before we board. I went to boarding gate E6 I think to inquire and the lady told me they're Richard's bay when I asked the following question she was so rude and her had flying all over the place, I couldn't understand how asking a question politely can change someone's attitude like that. Her name is Boitumelo Pelo. I'm flying on 17 February 7:10.
