I believe they are a related to a college program. If you applied for anything where you were asked if you wanted more information about going back to school that's where they got your phone #. In my case I applied for an auto loan...I answered a couple of the calls and said I was not interested , but they continue to call...
These people just called 3 times in a row the day after Christmas. My mom answered on the 3rd call while cooking Christmas dinner and they were calling about senior care. Unbelievable. 3 times in a row. For that.
