I was getting close to 50 calls a day from same company selling insurance, they use many different numbers to call from, all the same company.  I told them I am not interested and have been cussed out, told they were going to rape and kill my wife and so on so what i started doing is calling them back and harassing them.  I Iced down a six pack of beer and sat in my chair under my shade tree and spent 5 hours repeatedly calling them and after they answer I placed my phone next to my radio with Rush Linbaugh playing very loud.  The next day a supervisor from their company called and said if I would quit calling them they would stop calling me.  I haven't heard from them in 2 days now.  I guess these scammers do not appreciate conservative political talk radio.  too bad, I was having fun turning the tables on them.
