Calling for a "reference" for someone. Didn't identify the name of the company when they left a message.  I found it out by calling then back. I barely know the person in question.

Joan left a message addressed to me by name. Wants me to call her in reference to an Adam G.  Don't him from Adam.

Hi this message is for ________my name is Hillary I was calling you in regards to Sarah Johnson please call me back today at 855-202-7001 just mention reference number 13120531 thank you"

This is a debt collector They're trying to trick people.

Christina from this number called me at my work today, did not identify the company from which she was calling, saying it was on behalf of my sister in law.  Did not leave a business name, but left a reference number.  Called my SIL to make sure everyone was OK.  Appears to be on a student loan issue which has nothing to do with me, they have been in contact with SIL already last week.  There is absolutely no reason that this person or company should be calling my place of employment to discuss something that I am not involved with in any way shape or form.   I am not a signer, my husband is not a signer.
