I have always wanted to be able to call telemarketers back and discuss the weather. After all if I can talk to one of them about the weather for 5 minutes this in turns ensures that 4-5 people will not have the pleasure of slamming the phone down on these idiots. But instead you can call the group that speaks for telemarketing industry.
So if you want to give American Teleservices Association the group that advises the companies that interrupt your dinner, sleep, family discussions etc you can call them at 317-816-9336 [MetaFilter]
