I have to give full credit for this one to Melissa. I kept hearing her say “Actually, you called me yesterday.” There would be a pause and then she would hang up. It turns out she was using her favourite trick on another telemarketer. The next time you get a call from a telemarketer tell them that they called you yesterday. They’ll start backpedalling, maybe even say how it’s weird that they might have called you, then they’ll say sorry and hang up. I think it’s the one response that they aren’t expecting. And if they say that isn’t possible, then just tell them that it happened. Guarantted you have them off the phone in less than 25 seconds and they don’t call back.
