They have been calling multiple times a day for over 2 months. I called number back and left message that I have notified local police and will notify Federal Trade Commission.
I have been getting calls from this number every day around 5pm but never manage to catch it to say stop. I have tried calling the number back and it's disconnected. Today I got a missed call from an 877 number and when I called back it was Santana Energy. My google research on that company turns up scam complaints.
