********** Customer Service Experience

I would like to bring to Telkom's attention regarding the pathetic and ********** service I experienced from a call centre agent in the accounts and billings department. I work in an industry where we abide by the TCF Principles(treating customers fairly) by law most companies are supposed to abide by these principles, however your agent felt that she was more superior than a client which happens to be contributing to her salary every month. After speaking to her for more than 20mins I requested to speak to a supervisor as she was not sympathetic or empathetic in any way. She placed me on hold and comes back to tell me that her supervisor is busy on another call. I then requested to hold on and she tells me that there are other clients in the queue waiting to be assisted and she cannot place me on hold to wait for the supervisor. She then tells me those clients are important as if I am not important as a client and she cuts the call. I would like a formal apology from the agent as that is not how you treat clients. I would also like some sort of feedback or correspondence from her manager to assist me with my query as she is clearly useless and cannot do her job properly.
