I think the big key to answering a question when you don't have the info is to be honest, be like, I don't have the info on that right now, I'm not entirely sure, but let me talk to my team and get an answer for you. Whenever I was at my call center, we did that often on calls with customers, we said, may hold for a moment, and then we would talk to coworkers or maybe Google it, and we would get a good, clear, concrete answer. It's pretty important that you do not give information up that you are not 100% confident on, because then that customer could call back later and get conflicted information, and it's just generally not a good idea. So it's best to have your concrete answers and to talk to your peers and use your resources to get good answers so that you can give those to the customer.
