What kind of experience is it to be a telephone customer service?

Fortunately, the suffering is real, my voice and ears are heavily loaded, surrounded by computers, chattering voices, and boring mechanical repetition of some basic problems. There are many exotic flowers and plants, and there are many harassment, especially afraid of encountering them. I'm afraid of professional complainants. When you receive it, don't say the wrong thing. If you say something wrong, you will always complain and lose money or lose money.
