Do I use the Netflix trial month?

I got netflix quite spontaneously and didn't pay attention to whether I was using the netflix trial month.

It says (if the link doesn't work here again):

STARTS 9/11/20

Base

I'm actually pretty sure that I'm using the free month but just want to be sure.

Yes you do.

Yes. You will automatically receive the trial month when you create a new account

Okay thanks. The support meant that I didn't use it.
