Unwanted spam number from Carrington College to my cell phone - TAKE MY NUMBER OFF YOUR LIST

"Hi this is Lisa with the Green studies survey...blah blah blah....your free trip to the Bahamas"

Called twice and left no message.  I don't answer calls if I don't know the number because it's always spam! Adding this number to my long list of blocked calls.
