Had this happen to me when I was in IT. I got a cold transfer of an angry customer who wanted to talk to a guy who had a very similar name. I told the customer that they wanted the other guy, I was in the wrong department, and they wouldn’t believe me. They said “I know it’s you from yesterday, I recognize your voice!” How was I supposed to argue against that?? Eventually I convinced them and did a warm transfer to the correct guy. We do have similar voices…
