Canceling Internet Service After Paying the Bill

Hello,

I am a little confused about how the service period and service cancellation work and was wondering if someone could help me with it

My internet service period is from the 20th to the 19th of next month, and I pay my bills on the 6th.

I am planning on moving out of my current house on the 11th.

So my question is

Suppose I pay my November Bill for the service period Nov 20th to December 19th. Will I be able to continue to use my internet service until December 11th even if I cancel the internet service on November 20th?

Thank You
