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.
who the hell are these idiots anyway??? I get between 7-9 of these calls every single day. There is no end in site. I NEVER EVER answer these call any more I used to yrs ago this seems to be going on for several yrs now and as I read the different postings from the different numbers that call me I get an idea of what & who they are,(so I don't bother arguing with them) I read many posting when people say the more you ask them to be removed from the calling list they will just call double times, so why bother, I hope that one day this nite mare would end & they will stop calling.
