If you thought creation of the "Do Not Call Registry" had solved the problem of telemarketers bombarding people with unwanted calls, you thought wrong. Complaints about telemarketers have only continued to climb since the Federal Trade Commission established the registry 2003. They now stand at an all time high—almost 4 million in 2012--according to the FTC. What can you do to fight back? Plenty, say experts: You can use new technology that detects and deflects telemarketing calls automatically. You can deliberately drive telemarketers nuts, until they leave you alone. Or you can do both.
