If you've ever worked in retail or the like, perhaps in high school or college during the summer, you can just draw on those experiences. If you haven't, I'm sorry you missed out. If you can afford to hire, you will not find it at all difficult to find someone who is very good at this; half our economy in the US is oriented around this so there are a ton of people skilled in customer service. It is a skill, and handling the emotions is a big part of it. The thing that is going to make it difficult for you to teach yourself customer service on the job is that you are the founder so you have no detachment. In order to handle all this you have to be able to detach yourself behind a veil of professionalism and that's WAY easier when you can remind yourself that this is "just a job" and that you are "just representing someone else (the company)" and that this moment is just as much a success for you regardless of the outcome. None of that is actually true in your case so it's much harder. Hire someone to do customer support if you can afford to, and if you have kids be sure to encourage them to take some random summer job working with the public in high school at least once.
