I have been to an enterprise management company to do telemarketing, but now I forget. In other words, the salesperson should keep the customer's information record after each call.

Hello, I'm glad to answer your question. Salespeople need to be patient, so does telemarketing. Customer information should be recorded after each telemarketing, so as to make a good customer file. When taking notes, you can record your name, age, residence address, occupation and company address. There is no guarantee that every customer will answer you one by one, but at least you should listen patiently and speak politely.
