These guys called again this morning looking for "David Lee" with a toll free #. 888-694-2240. There are people answering the phone.
Phone call for David Lee include 214-705-3703 (when I asked, a lady said David Lee signed up for baby website), 888-694-2240, 302-394-6827 (classes careers) 423-544-7389.
Since there's no David Lee, I don't know whether it's a scam or somebody signed up something and put my phone #, or he put a wrong #.

I think it's a scam because these caller are totally different.

So annoying. Hopefully, government agencies can crack down this as the one they did to "car warranty" scam.
