Extremely rude call centre agent

I have no choice but to report this to someone, I contacted the SARS call centre today regarding transfer duty refunds, only to obtain information so that I would be able to assist and for the benefit of my client. I was met with a woman on the phone who didn't even identify herself audibly. She preceded to tell me, in the rudest possible way, how I had no authority to even enquire about anything as I am only a secretary. I completely understand protocol and what she was saying but she immediately preceded to rant excessively without giving me a chance to speak, and I phoned them! I really hope that they actually do listen to the recordings of the telephone calls, I in tern was never rude to her, not once. I kept my cool despite her steamroller approach. I did not realise that my asking for information would result in receiving a scolding attack on my person. My only regret is that I did not get her name. In my opinion she is unfit to do her job and really does damage to the image of SARS I respect.
