I had someone call asking about my security system and pretending they were trying to give me a free trial. I of course did not answer any questions and hung up on them, but "coincidentally" my car was broken into a few days later & they took my garage opener. So I looked on my phone for recent unknown calls to add it to the police report, & this was one of the numbers I couldn't account for. IDK If the police will look into it, as the cop was a jerk when we called & just blamed us for leaving the car door open. Anyway.... Warning: if someone calls asking about your Security, don't tell them anything! I'm sure they're trying to find out if/how they can break in!
