Fred really did a great job

I received a call from this business 904 396 3916 and they hung up. So when I called back and asked them what type of business they were they said I only answer the phones I need your number. I asked for a supervisor and refused to give my name and the supervisor refused to tell me what type of business this was because I refused to give her my phone number. I have several phone numbers and believe this is a collection agency illegally harassing one of my employees at their place of employment, please investigate this because this isn't a typing service.
