The reason a large portion of the people are having trouble with this number is because this number is being "Spoofed" by Delta Outsource Group, a collection agency located in O'Fallon, MO.  They will try and gather enough information to create an account.  Many bank accounts have been drained by this establishment and many "Spoofed" phone numbers have been fraudulently used to aquire information.
This not only hurts people by the harrassment, but also hurts the establishment that the number belongs to.

"you receive a free cruise ...."

Called at 1pm EDT, no message.  There are people that say this is for a cruise.  I got a call from another cruise company telling me I could get a free cruise from when I signed up at a Pacers game.  Could be related.

The other company was Sundance Vacations.  Stop selling my info Sundance!

Missed a call - no message was left.
