I would basically describe Suddenlink/Altice as "Not quite as terrible as their competition." All telecom companies are basically monopolies. They all charge as much as they can get away with. Wherever you are, you probably have up to two companies to choose from. AT&T is always the most expensive. The other company is usually slightly cheaper than AT&T. As it is with Altice/Suddenlink.
Starting this year, they jacked up their illegal "internet enhancement fee" another dollar a month and doubled my monthly price while reducing the data cap from 250GB to 150GB. How's that for a greedy company? My only alternative is to pay more even for AT&T or go without internet altogether.
Just look at all the bad 1 Star reviews here. SUDDENLINK SUX
When I had problems with Suddenlink, I contacted the FCC, assuming they would look into the issue. To make a long story short, that's when I leaned the FCC does not enforce regulations. That's the FTC which handles enforcement. But the FTC is overloaded with more important issues than to deal with us lowly consumer surfs.
Suddenlink/Altice is owned by some gazillionaire living in Switzerland. Good luck trying to fight a company like that. They don't care because their customers have no choice but to select them or another crooked utility. That's capitalism in the good ol' USofA!
UPDATE April 2021:
A friend gave me some tips on how to finagle a discount out of Suddenlink. Now I pay $45/mo for more data and faster than I'll ever use. I'd describe here how to get it for yourself, but to say it was complicated would be a huge understatement. So all I can really say is that it can be done, but you'll need luck and a whole lot of patience and perseverance.
