I work in a company that handles immigration or study abroad, and I am responsible for calling potential customers on my own initiative. How should I communicate with my customers?

First of all, we must analyze the intentions of potential customers and make plans according to the results. Not too specific, of course. After all, it's just a potential customer.

In fact, the communication between people is not so complicated. He needs to serve you and provide services.

Just say it directly. It is normal to be rejected. Don't be too emotional.

Besides, someone in the company should take you there, right?
