Hello, I just had an incoming call come in from a collection agency, using an unidentified number (unknown name, unknown number), I answered it because we have a few friends that have unidentified numbers, so it is just a habit to answer it. Well, the lady on the other end was asking for my Fiance, so I asked what the call was about, and she wouldn't tell me anything, not to mention she started getting nasty with me, so I told her that I will not pass this message on to her then hung up on her. What can I do if this company calls again? Can I report this as a harrassing call.
