Netflix coupon expired, but can continue watching?

I had Netflix for 1 month with the gifts card so 2 months (with the free month) now the months have expired but somehow I can still watch. And I have not entered any bank details and no new gifts card. Do I have to quit because I thought Ivan hears it by itself and there's something wrong with the last payment.

So my question is has Netflix for 2 months with the gifts card these 2 months have expired but I can still watch.

How so
