Problem is, you have to find them, and you have to sue them in their home town, not yours. You might me able to recoop your costs of the flight out there, though. Bigger problem is that most of these people are not legitimate telemarketers. They are scam artists with spoofed numbers, so it's much more difficult to track them down and sue them or get them arrested.
2010-03-19 9:34A CST Caller hung up on answering machine.
2010-03-19 9:35A CST I picked up phone, but said nothing.
Caller said "Hello?" and I answered, "Hello. Who's calling, please?" Caller identified self as Bob Jackson and asked for my spouse. I said, "What company, please?". He ignored my question and asked a question about 1-800-Flowers. I interrupted him saying, "I'll be answering no questions unless you answer mine." Caller yelled at me saying, "You know that's some way to run a business." and hung up.
They called a private, residential number which is on all do-not-call lists.
