Stop calling!!!!!!!!!

We have received 2 calls from this phone number. No message just hang ups.

Have received a call from this number twice. No message. It tracks to an actual person, but I haven't tried calling the number yet.

This is a VIVANT phone number, they are a home security system company.  We recieved a knock on our door at about 7pm and they were installing the system for free and wanted us to be a model for the neighborhood.  We asked what day would be good and they said they had to do it that night. Aginst my better judgement we let them. They didnt finish until midnight.  After doing further research the next day I found out that they were in a huge class action lawsuit for installing the product wrong and causing house fires among other bad busines practices.  I immediatly cancelled.  Now they call wanting us to come back.

got the phone call from office, I did not answer, no voice mail left either.
I don't think I should pay attention to this call...

This man keeps calling the house asking about our security system. Says he wants us to upgrade our current system, then asks what type we have, if it's through the phone line or digital. if we have a dog and if the dog is kept inside or out. if our system is monitered and if we have sensors on the doors and windows or just the door. Asks what hours my husband works. We have tried calling the number back, but the number doesn't take incoming calls. Not a good way to get business.
