Scum ball , bill collector, calling for a person that is unknown .

Returned call. Transferred to 'Switchboard' who states there are several companies in the building and she cannot tell me who call originated from. Of course not.

This is a collection agency... They collect for multiple companies.  If you give them your telephone number they will tell you whom they are calling for and what company they are attempting to collect a debt for.   I gave them the number they called, but NOT my name (just made one up on the fly).  Once they told me whom they were calling for (NOT ME) I informed them they had the wrong number and ask that they remove my number from there collections list.... LETS SEE what happens.

Bill collector for AT&T

Received a call this evening. No message left. I am dealing with a credit collector re medical bills but don't know what this is.

called left no message, could hear like noise from a call  center in the background...
I suspect a bill collector I am fighting a collection notice ....

No message left just called and hung up

I called this number back and asked who I was calling. She would not tell me. I was then transferred to someone else and asked, "Who is this?" and the response was "Who are you looking for?" Sounds like a bill collector or scammer.
