8007523916 / 800-752-3916 Reverse Phone Lookup

My son is receiving these calls multiple times a day on his cell phone. He hits the end button and they call right back. I answered the last call and went through the options. If you hit number 4 it will take you to an agent. I asked the agent what company they were calling from and she said Regional Adjustment Bureau. I told the her that they are calling the wrong number and to remove it from their database.
