Pathetic Employee Attitude

This person that has an attitude problem and needs to know how to speak to clients. She phones me says she's working for Standard Bank and that she wants to know which branch do I bank with. No verification questions and when I asked her who she is because she's asking me personal questions she told me I wasn't listening to her and was very hostile. She said I already did the verification online. Nothing about the call sounded right. She then explained why she was asking me to which I responded that I sent all my documents via the email address provided. You don't just call people asking them banking information and when they question it you have an attitude. If my money gets ****** will you have an attitude then???
