Who called from 8024847489

Another "second notice that your vehicle warranty has expired" scam. Only a dead-end recording. Keeps calling in spite of our listing on the do not call list

Called at 12:59 7/2/08 on my cell, left no message.  I won't call back.  I was getting these calls over a week ago but not this same number.  A web search showed they are both vehicle warranty scams.  I never pick calls from area codes I don't know.  I always do a google search and inevitably find them to be scammers.

I had THE SAME exact # call me. The same exact day but arounf 12:35. I tried calling back but it was dissconnected. How do they get random #s to call?
