Rude and poor service

I went in for a Sim swap at Vodacom 4U at Carlton center for a Sim swap. The process only took 10 minutes but I left the store 30 minutes later. The store had was not busy with 2 agents free, the first I went to redirected me to the 2nd. The agent (Zama) was not showing interest in helping me even after asking for her name and tried initiating a conversation. After sitting for 5 mins, Zama said to her colleague that she will not help me as she felt was being rushed by her colleague who used the same credentials to log into the system. From there she just said that I will be assisted by another agent and imidiately got up and went to the till to go play with her phone. I had to wait a few more minutes to be assisted by another agent who had the very same attitude of not being keen on assisting me.
