BAD customer service from Telkom Brooklyn Branch

I really had a bad experience at Telkom Brooklyn Branch. I went there on the 8 of May at 3:40pm , I wanted to do a simswap. I join the que outside the store, while I was on the que, a consultant (Tersia Dhlamini) came to us , she didn’t greet us,she only said to me I will be the last client to be assisted and I must make sure that there is no one joining the que behind me because they will be closing soon. After waiting for more than 30 minutes outside, she came back to the que and she started by shouting at me , asking me why there’s two more clients waiting as if it was my responsibility to turn customers away. So she decided to punish me by assisting another client who came after me and when I asked her she told me to go back and wait outside.She also said to me that the system that she is using it doesn’t allow her to do a sim swap. So I decided to leave because I didn’t feel welcomed as a client who has contract with telkom , first of all she didn’t greet me, secondly she shouted at me and lastly she was not willing to help me.....I’m so angry because my contract account is up to date, but I’m stuck, I can’t use my phone and people can’t get hold of me.This is so BAD
