I answered the phone when this number called, and received no answer. So I called the number back, and sure enough, it is Target's financial department. Only problem is I don't have a Target card.
I guess it was just a mistake on their end, but they keep on calling, and I can't talk to anyone to get my number removed.
I work for Target so when they called I answered, because it said TARGET TFS on my answering machine, I still don't know what it was but my store swears it wasn't them.
