Bad customer service

This morning while at the counter getting my boarding pass flying from Cape Town to King Shaka I was assisted by a Mpho I am skeptical of even saying a lady because of an unlady like attitude she gave me. She asked if I had a bag to check in and I rep**** by saying I think I'm gonna sky check my bag. Then I proceeded to show her the size of my bag and she looked at it and proceeded to print my boarding pass. Her colleague 2 counters from her pointed out if she saw I was carrying a bag and whether I should check in the bag because its big according to her. Mpho responded by saying I told her I didn't want to check it in to which I responded I wasn't pleased with her choice of words I didn't say I don't want to check in my bag I said I think I'm going to sky check it. She then told her colleague that I gave her attitude when she asked me to remove my mask so she could see my face. I don't know how I l gave her attitude because its protocol I've flown a couple of times since lockdown I know I have to show my face when showing the teller my ID so they can verify its me. I told her colleague that maybe she wanted me to smile I don't know. Then Mpho proceded to hurl insults at me while I was walking away. Her attitude disgusted me especially so early in the morning. I am so disappointed with the treatment I received. I always wonder how someone can have an attitude when her job is to work with people, that always leaves me baflled.
