I have started hanging up FIRST, the second they say the word warranty or ask about my vehicle, I just hang up first, that's what they are going to do to you the minute you say no.
I must say, these are one of the most persistent bunch of telemarketers/scammers I've ever seen. I never pick up on a number I don't recognize, & realize that most of these crooks are spoofing actual numbers. Usually if I don't pick up they stop calling after one or two times. I guess they assume they got a "dead" number. Not these guys. They have called four times in the past 5 hours. I don't answer and they don't leave a message, so no one is getting anywhere. The only time wasted is theirs. I may block their number if they call anymore today. Enough is enough.
Told me to screwanmyself so I did with a english cucumber.. was the best 67 cents ever spent , then I washed it and made a tossed salad for the inlaws. I passed on the salad, but the liver and fava beans were yummy. I poured a glass of chianti and added the # to my block list :o)
