This is what this case is about. TWC did this to me. They leased me a Motorola SB6121 that is capable of doing 100Mbps. They then "upgraded" my speed to 200Mbps, but kept the price the same. The 100Mbps tier then became $10/mo. less than the 200Mbps tier. At that point, they were ripping me off for $10/mo. I confronted customer support with a well-crafted chat message pointing this out, with links to their own specs. They moved me to the 100Mbps tier and credited me $80 or $90 for overcharging me, and didn't fight about it at all. It's like they made damn sure I didn't engage the Streisand Effect.
