re: How do you deal with telemarketing spam?

Had a neighbor who just bought a house and some floor salesman kept calling him about new flooring. He must have told him no 4-5x. One day the salesman calls and my neighbor was extremely bored and starts bullshitting with the guy. He tells the guy he may be interested and had $15k to blow and the salesman gets extremely excited. Neighbor proceeds to break out the tape measure and measure every single room in his house and makes the guy start giving cash quotes per room. He keeps the guy on the phone for atleast 2 hours and they come to a deal. When its time to pay up with a credit card, neighbor tells him his card number is 123-456-789 and so on. Seller thinks its a joke, neighbor then tells him the same number and seller starts getting aggravated. Neighbor then tells seller that he wasnt really interested and he should have listened the first time and cancels the sell. Seller gets EXTREMELY mad and begin cussing out said neighbor, neighbor laughs and hangs up
