These are scam artists asking for your personal information. They tell you that you registered for a john deer riding lawn mower and try to sign you up for a home security system. They are trying to steal your identity! Beware!
This number had been calling me for 2 weeks. I finally answered and they told me I registered for a John Deer lawn mower, and was part of 2% of those people chosen for a free security system. The guy went as far as setting a time and date to come install it free of charge and all fees waved but never showed. I've tried calling the number back and it's busy or tells you all circuits are busy. BEWARE SCAM!!!!!
