After receiving the phone call, you should first report your name and some basic information and ask, "Are you the owner of XX?" Then after the other person answers, ask the question you want to consult, and finally let the other person hang up.
Speak generously, concisely and politely. In fact, the first nervousness may be inevitable, but as long as you try to keep smooth and don't stutter too much, people are actually responsible for it. You just need to ask your question concisely, and the other person will know what information you need to know.
Calling the leaders is inevitable in our future life and study, especially after going to college and entering the society, we have to deal with our own affairs, which makes it even more necessary to study. Practice from now on, don't worry. Now that someone has agreed, try to be generous. Get up the courage to pick up the receiver first, and try to overcome it even if you are nervous. I believe you can.
Hehe, although I have said so much, it's actually not a terrible thing, is it? Give it a try. There is always a first time for everything.
