I got a call from this number: 704 337 2980. It IS from a benefit center, however... I believe this is a benefit center that is serving many companies. I work for General Dynamics Electric Boat and called the benefit center with an issue. They just called me back to let me know they are still working on my issue.

My point is, that if you work for a large company, then this benefits center may be servicing your company, not necessarily just Target.
