Discovery Employee using their discovery postion to get details from clients for Personal reasons

A lady from Discovery just called me from ***. She wanted to know if she had reached the correct company which i confirmed and then she asked if she could confirm our address, which i duly obliged and confirmed. I then asked her why she wanted to confirm, as it felt a bit odd. She then admitted that she was confirming it for a friend who heard we were looking to employ "drivers". I said to her we were not employing anybody. I then asked her who is her friend who told her, and after much giggling she admitted it was a "Thapelo". I find it quite invasive that an employee of discovery can abuse their position to obtain information for friends. Not I am worried about who is now going to just arrive at my address because she is obviously going to share it. Please investigate - Call originated at 12 Feb 2020 at 14:34pm and lasted 2 min and 48 sec. True caller identified it a Discovery Gap Cover ***.
