Who called from 3133555249

I received this call on my work phone on 8/9/13 at 10:24am. Left a blank 3 second long vm and hung up. I never put my work # down on anything.

Got a vm on my work phone telling me my car warranty was about to expire and then asking if the year of my car was between 2005 and 2012.

I posted a car for sale on craigslist, used my cell number in the posting, the only time I've made my cell number public, now I'm getting stupid calls!

I received the call this morning. I do not even own a car.

Called my number today, 13 AUG 2013 at 9:51AM CST. Don't know anything about using Carmax and no voicemail.
