I received a call from a 000-000-0000 number and they left a message for me to call this 877-239-8567 number back with a account number.  I do not know who this could be and no company information left in message

I received a call on my home phone and my daughter's phone from this number.  Referred to me by my first name but referred to himself as Mr. Walker.  Interesting!  Left a message that I should return the call.

This number belongs to Union Adjustments.  A Collection Agency in Burbank Ca.

It is Union Adjustments - a Collection Agency

I have gotten several voicemails left over the past couple of months.  In each case, the caller leaves a voicemail saying "<Garbled Name>, this is Mr. Walker.  You can reach me at 877-239-8567."  I finally called him back and Mr. Walker himself answered.  It sounded like he was working at a desk (but not a loud call center).  When I told him the number that was being called, he told me the name of the person he was looking for at that number.

Now that I listen to all my past messages on that phone, I just noticed that I had a couple of other calls telling me to call that same number.

One is an automated call which announces itself as an "important call" that is "not a telemarketing call" and asks me to call back with a reference and account number.

The other is far more interesting.  It's some woman who asks for the same guy that Mr. Walker did, but it's from a woman who says she's the sister of the person she's asking for and says she's been looking for her everywhere, hopes this is the right number and that she really misses her.

So maybe this number is for a private investigator.

I got a message on my cell phone from a 000-000-0000 number, but this phone number was listed for me to call back with an account number, but no company name or anything given?  Would like to know who it is before I call!!!
