Loan and IRS Scams; make the Telecoms liable

On a daily basis I receive multiple cell phone calls from those who 1) tell me I'm approved for a debt consolidation loan (or some other reason) or 2) they're from the IRS and I must address the problem immediately.  

They are obviously financial scamsters, but most use what appear to be toll-free numbers.  The telecoms make millions of dollars off these scamsters and folks like you and me suffer the consequences.  It's highly unlikely that the telecoms don't know that lines they sell are being used for fraud and theft.  Lets motivate our legislators to make the Telecoms financially liable for not performing due diligence before they sell the lines.  One thing for sure, the FCC or other government agencies are completely impotent, incompetent or just plain unwilling to effectively address this concern.
