Bad Attitude and rude responses

Bad Attitude

I called the call centre ********** and got through to Mmathapelo, who gave me attitude from the onset, she did not even want to check my details, she just gave me an email address that I was supposed to send an SMS to, "I quote". upon my confussion I asked if there was no one to assist me or someone she could transfer me to, and she said "NO", I have send a message to FNB social media and was advised that for real time I assistance, I needed to contact the call centre with the number provided above. As confused as I was about the attitude, I asked to get Mmathapelo's surname, and she asked how her surname had anything to do with the call, I mean I am a client that needs to be assisted and instead I got a very bad attitude, really really bad, if I had started being rude I would understand that maybe she needed to react to how I was treating her, however none of that happened, instead I was rudely spoken to for just asking for information. I requested for her surname to be spelled and was given attitude still, she spelled it so fast that I couldn't get it, I asked twice but got the same attitude, I requested to speak to a supervisor, and was put on hold and was told "Supervisors are in a meeting", which was not true at all. Are FNB employees really allowed to speak rudely to customers, client who are not even fighting at all???
