I just logged onto the fios site and, when reviewing my account, saw that I could change from my 50/50 speed internet to 75/75 at no cost. See screen shot (which I'm glad I took!).
When I clicked to place the order, I saw a new price of $84.99/month appear (I previously only paid $59.99/month). See the other screen shot.
Has this happened to you? Anyone know if this is a glitch?
