Internet company

This evening when I am watching TV, somebody knock on the door all of the sudden. I thought it is my brother, so I went to open the door. To my surprise, it is not my brother, but it is someone from the internet company. I do not know why the internet company wants to find us. She asks a lot about our internet stuffs, and it seems like she is trying to ask for more information.

I thought it is just a salesperson trying to introduce the internet product. But we already have internet, and I already told her I have internet. Why would she still want to ask me for more information? I am afraid that if I leak more information, my father will scold me, becauseI m alwys the one getting into trouble. So I told her that I am not the one signing up fo the internet, and it is my father who is signing up for the internet, and I told her that I do not have any knowledge about these internet stuffs, and is unable to contribute more information.

I thought this could chase the salesperson away, but instead, she said that she is going to come again. At this point of time, I feel really scared. I do not know what might happen if she return again. Did we do anything wrong? If it is just ordinary salesperson, why does he wants to come back again? Moreover, we already have the internet. Why do they still look for us?
