<human>: Could you distill the essence of the text into 1-3 sentences?

I recent moved and set up internet service with a provider in the area. I purchase my own modem and router to avoid monthly fees. I installed the hardware on my own.

Before moving I had made an appointment for a house visit to set up the service and decided to do it myself. I simply called the provider for my account number and canceled the home service. The account number was all I needed and was done with it.

A few months passed, I never got a bill. I attempted to log into my account with the provider and they have no record of it. They even called me at one point and asked why I canceled the home visit. I told the rep that I took care of it myself and gave him the service start date so that they could start billing. No bill, and I still have service. 

What should I do? I like the free service but if I have problems in the future or they find out, I don't want to be at the end of a very angry phone call (or worse). Thoughts, concerns, general advice from an internet provider rep? (Fingers crossed)
<bot>: I am getting free internet from a provider without their knowledge. I don't know if I should do the right thing (The $40/month thing), or the free thing (AKA the wrong thing).
