When i called them it said something about tmobile or sprint diversified sponsor link

Had a missed call at 1:00 pm - no message.  Called back and got Diversified Consultants.  It's supposedly a Sprint collections agency.  I have NEVER had a Sprint account and the "verification address" she gave me was not one I had ever lived at.  She did, however, have the last four digits of my social security number.  I had quite the nasty conversation with the lady.  She wanted me to fill out a report online, to which I declined.  I asked her to send me documents by mail to which she said she could not.  I told her I refused to fill out any information on any website.  She got nasty with me and hung up.  I'm unsure if this is a scam or not, but I would not trust it to not be a scam.

got a call from this number as well..probably a creditor.
