I want closed caption on my tv - DirecTV

I called last night and got a person that was supposed to know how to help me. I had to go through two people that asked me the same questions. Then I got this girl and she kept telling me to do this and that and nothing helped, it took a long time and I was getting no where. Finally I told her this was talking too long and I wasn'the being helped and hung up. She didn'the know how to help me and I am very upset. I can nor believe that this is such a big problem to get CC.

What do I do?
