Kathryn Summer left a message on my voicemail from this number. She said to call her due to a "very important business matter."

I'll post more if I get an update.

I just got a call from that same number, with that same name. What is it?

Not sure who this person is.  Just received call at work and the call back did not identify self.  Katherine left a message as urgent.  Don't think it is wise to call back a person who is afraid to identify the company she works with.

The phone number is from a debt collection agency named FCO. They do not like to reveal the company name so that you will call them back so they can get comfirmation that they are calling the right person. Also they do not like to say the reason they are calling because the information is confidential, and should not be just left on a message. They will call until you call them back. My guess is that you have some debt that is not being paid, if not then you need to clarify it with them. If you do have debt then they can set up payments for you, that's what I did. They will try to make you pay the debt in whole, which is cheaper, but not likely. You just have to make sure that payments are made, you cannot miss one. They are willing to work with you, they just want what is owed to them.

I received a call from this number they had my name and they said that I should not ignore the message and that I need to call with a reference number that it was very important.
