Wrong numbers are already too much of a hassle to deal with. No matter what the other person never seems to understand that they are the ones that messed up. Usually you don't even get an apology. Then they just call back ten seconds later and you have to go through the whole situation again. "Just stop dialing the number you are dialing. It will never be right."
This person definitely did not understand what was going on. What do they mean "what is the right number?" as if this poor soul has any idea what's going on in their life and who they should be calling. It's not anyone's responsible to deal with random slow people. If you're a random slow person and I have to deal with you, you're going to get cussed out.
