Who called from 3863614000

These scammers make their money from the monthly monitoring fees customers will be paying for their "free" security system after it is installed.

I just got a call from this number, did not answer it.  Called it back from a landline and was told number not in service.  Must be someone wanting to sell me something.  Call is now blocked.

This is a spam advertising call or some promotion to my cell.  Unwanted, unneeded and I hung up before spiel started in depth

Called cell phone once and left no message. I read 800 notes.  Blocking the number on my iPhone5 was fast and easy...  tap, tap, done.

Called my textfree number and when i call it back it says its not a working number
