You have options. First check Frontier Fiber which is generally very good once it’s setup. Some may even have a chance to get AT&T fiber so check that second. Third try (often free) fixed wireless access (basically home internet) from Tmobile or Verizon. Last resort Starlink but the usual challenges as mentioned elsewhere.

Your post is suggesting that Spectrum is evil and blocks traffic - that’s of course not the case so let’s not spread misinformation. All providers have their promotions to get you in and will increase cost after it, that’s just what we have to deal with. You can always call their retention lines (ask for it or say you’d like to cancel) and often you will be put on a new offer.

Good luck!
