call Spectrum for a quote so I can then call AT&T and harass them into giving me the correct price for another year.

It's a shitty business model. Over the years I've found that in order to get the most out of Spectrum it is necessary to be a royal asshole and live in their phones. Here in this locale, Spectrum contracted with the local schools to be their ISP, so Spectrum became a utility just like water, power, etc. We even have a complaint form on our official county's website to facilitate being a royal asshole when necessary.
