Pathetic Attitude From Call Centre Agent

I got a call today from ABSA Credit card division. Consultants name was Gladwin. Let me start off by saying the number came up on my truecaller as spam, ABSA credit card and it was also from a cell number. After having a bad experience with a previous **** call, I'm very nervous about banks calling me and asking me to verify my information. Gladwin started being rude and having an attitude with me when I asked him for any further security to verify themselves. I do not appreciate being spoken to in a condescending tone. I don't care if you are the king of England.

ABSA please train your staff to be better! If I as the client request for further security measures to make sure that I am indeed speaking to someone verified from the bank, I have a right to that. I don't need teenage attitude problems with your work force!
