So, Verizon increased my bill by $5, made me call in, then subjected me to some "additional services" pitches before finally saying "there's something we can do" and "re-enrolling" me so I can have the price I originally agreed to for another two years.
$60/year isn't a crushing amount of money for me right now, but of course, it very well could be for people that can't take the time to call and insist that they revert the price change. Verizon isn't even the worst ISP in this regard; Comcast was around $90/month for us, and when they raised prices, there was truly nothing you could do.
But this business standard, which feels new-ish to me though I could be wrong, in which you only get what you agreed to if you have the time and energy to apply pressure to enforce it, disgusts me.
