Who called from 2532143420

Called from a National Insurance Company, said that 2016 laws could drastically reduce my insurance rates.  When I asked who she was and why they were calling me, she immediately said "Sorry, you didn't qualify" and hung up abruptly.  If she knew I didn't qualify why did she call me?

Phone said hello twice and hung up. Sounds suspicious

Why is there a DO Not Call list?? It isn't working!!!!

Called me I said hello 3 times at which point I was hanging up and a woman finally replied saying she was going to discount my auto insurance. But as soon as she asked my name I hung up. She obviously was not affiliated with my company or would know my name.

Called the number back but recording said not a working number. May be a "Spoof" number used by someone for any reason. Be careful if you answer.
