Does the current telemarketing feel like a liar, but it is hard to convince.

Your idea is wrong. I have been doing telemarketing for foreign information in Shenzhen for several years and shared some experiences. I think when you recommend your products to customers first, you should have a detailed understanding of the products, and you should have trust and firm belief in your products, so as to impress your customers. If you have no confidence in your product, you will be like a liar, just like you said. You should know that you are doing it for yourself.
