If you cold-call me, I will spend the first few minutes feeding you false information. I will deliberately drag out the process, and at about 12min into the call, I will confess that I've been faking everything. At this point, I will attempt to tilt you so that you lose your temper and start cursing at me. On a really good day, you'll be so angry that your manager will have to come onto the call. I will feed them a few minutes of fake information, then attempt to tilt them as well. On the best days, you and your manager will sit around a reverse phone book and dox me, looking to find ways to intimidate or control me while I laugh and attempt to keep you on the line. My record is 52min, lasting over multiple phone calls, ending in a dramatic reading of a maths paper over the phone to a speakerphone consisting of three levels of management.<p>I want your business to fail if you cold-call.
