"Lauren" from National Auto Warranty Service.  Initially seemed to be associated or connected with the dealership I purchased my vehicle, but it got fishy pretty quick.  Informing me that my warranty was expired and pushing hard to get me to re-enroll so that warranty would cover the cost of auto repairs.  Asked how many miles were on my vehicle after this.  I explained that the maintenance costs are lower than the cost of the warranty.  Very rude and pushy, ended up hanging up on me.  I'm on the do-not-call list, and they somehow acquired my work phone number.  It's possible that this is a scam.
