This morning, I took my car in for the replacement of wiper blades. A young lady called Desree Kekana welcomed me, and while I was telling her that they must call Fleet Africa for an authority, she immediately called another lady . The other lady's customer service was just horrible. She instructed Desree not to release the car in case Fleet Africa does not pay. She said this in a very condescending and disrespectful manner. Their deal with Fleet Africa is not supposed to be my problem. After about ten minutes I went back to her just to ask her if she realized that she was not supposed to talk to me in that manner as a paying customer, but she saw nothing wrong with her action. I suggest that she must go for customer service training or not be allowed to deal with customers at all.
