This number has called me 5 times in the last two days and that was after I requested to be removed from their call list..................And the Do Not Call Registry is nothing but a joke.

Put the blame where it really lay's, with the criminals and illegal telemarketers.
The DNC works just fine. It is for telemarketers only and honest business does indeed abide by it. It is the criminals (which includes illegal telemarketers), frauds and scammers that do not. However, the Fed. DNC does not cover some survey's, Political or Charities.  You would need to check your states DNC laws to see if these are under your states DNC laws.  The fact remains that they are not automatic call blockers though and can not protect you from the calls that are criminal, illegal or fraudulent.

Do consider maybe getting a call blocking device or phone..  You can google them and many are around $60.00 or so.

Well said Grandpa...

they call 3-5 times a day and do not leave a message

The CIA already knows you're growing dope in your basement. The high electricity bill tipped them off. ;)
