"Senior Benefits" phoned my house at 04:00AM! No message left. I will not call them back, as I don't want to give them the satisfaction that they reached and irrrrrritated someone.
Don't call back this number or answer any questions on opt-out option. This just verifies your number to criminals. Seems to be exclusive to virgin mobile users.
This number has called me twice. I did not answer and they did not leave a message. I do not know how they got my number, and I do not want them to call me ever again.
