When will my service be fully disconnected?

Contacted Comcast to cancel my service because I’m relocated to Europe, and the chat agent told me that my service will be ended on 11/2, but I’m still be connected to the service up to now. Wondering if the internet service will be terminated right after I request the cancellation or it will take few days?

I don’t want to be charged for a whole billing cycle since I’m leaving middle of Nov.

Thanks
