Poor and rude customers service from Ethiopian airlines counter at the Cape Town airport

I would like to report the very bad service my niece received today at the Cape Town airport at the check in desk. 1. Since yesterday night I tried to check her in online it wasn't going through and giving me this message: "your booking has been found but some elements are not yet opened for check in. I then thought ok maybe because it's the night before. 2. Today since 9h00 I started to check her in online... I got the same error message. I swapped from laptop to my phone vice versa same thing. 3. I then called a uber for her to take to the airport. 4. She got at the airport at 13h35 and goes straight to the first counter, and apologised for being late and presented her passport. 5. The 1st lady she speaks to told her to go to the next counter quickly. When she get there tbis one tells her you are late there is nothing i can do for you go back to the lady who sent you if she agrees that I take you then you come back to me. 6. She goes back to the lady and the lady started to be rude with her then my niece called me and I requested to speak to the lady... She picks up the phone I greeting her and asked her what was happening and she started shouted at me while am trying to explain that my niece is pregnant and its not too late to assist her. You can check her in and leave her luggage I will send it with next flight...I also tried to explain that I have been trying to check her in online since this morning the system was not working..She shouted at me that it's not her problem that my niece is late and they cannot allow her and that the flight is closed and she put the phone down on me. 6. I called my niece back and asked her to give the phone to the first lady she spoke to. And that lady told her she doesn't speak over the phone she doesn't have anything to tell me... and she put her earphones on and told her: "you are late you are late and you need to pay R3350 penalties fees to change your ticket for tomorrow.. 7. I asked my niece to take both their names...they didn't have name badges with them They wasted her time even throwing from one counter to another while she is pregnant put the phone down on me and put on their earphone wrote the price on the piece of paper and pushed the paper to her saying if you have money we change your ticket if you don't there is not her we can do...then assisted other passengers, left her there and closed their counter and left i had to cancel my appointment with my doctor and run to the airport to fetch her...
