Why should I pay an ETF for cancelling poor quality AT&T internet service within 90 days?

I'm a longtime five cell phone ATT customer who moved into a new home. We added Direct TV and internet. The installer apologized for the poor signal quality of the DSL which barely registered above 1.2. His supervisor called me later to say he noticed the poor signal and wanted also to apologize but that the neighborhood would be getting new fiber optic cable in the coming year.

Our service was so slow and intermittent that we could hardly use it for my home office. I called Spectrum to install cable service and now am back in the 60 speed fast lane.

When I called to cancel my ATT internet, I was informed I would have to pay an early termination fee. I pleaded the case that the service was so poor that it was unusable and that I had give it nearly 90 days trial.

I am a small business owner who takes great pride in customer service. I would never charge a customer a fee for a  product that was inadequate - especially if that customer was continuing to spend over $400 a month for my other services!
