Just wondering who is calling

I am registered on the do not call list, yet I continue to get these annoying calls trying to get me to invest in stocks. Another scam I can do without. Surely there must be a way to stop these type calls & they should be classified as scam crimes punishable by law.

I keep getting calls from this number and they won't stop.I am sick of it.

Receiving calls from this number we don't recognize.  I answered today to find out who they are.  A guy by the name of Paul stated they are with UC Stocks.  

Guy called today asking for my husband.  I told him we are on the DNC registry and he said he's not selling anything.  I said he's not in our lives and not to call again.  We got a similar call about a month ago.  He said he'd call back 'cause he wanted to talk with my husband, not me.
