"JON" from home sercurity system

It was Jennifer(with a thick Indian accent) trying to sell home security systems.

This # has called on 1/19-1/21 and also 1/25 today. I only use this phone for work when I'm out of town. I don't use me cell. I never pick up and there is never a voice mail. They just hang up. I called it back, I get a voice mail saying the reps are busy. They will call back in the next day.....blah ,blah. Doesn't state the company. Please don't call back, scam.
