Spectrum Internet

It seems that when Spectrum bought TWC they made the base internet speed at 100Mbps at $69.99, which is an insane amount of money if you're not splitting this with anyone.

In TWC days I would get 12 month promotions for $39.99 and if I called the retentions department they would (most of the time) extend it and give me no beef.

Now I tried calling Spectrum and they wouldn't budge and even their retentions department was super mean. I threatened to cancel (which used to work under TWC) and rep was all ok with going ahead with cancelling.

DSL is slow here and I don't have FIOS in the area (L.A.)

Is there anything I can do? I don't mind if the speed is 50Mbps. It's insane how aggressive Spectrum is since they have a monopoly.
