At that point I actually noticed the fee (I hadn't really looked before that) and so I went in to complain. Here was basically my conversation:
Why did you raise the modem fee in January?
Because we hadn't raised it in a while?
Did you give me better service?
No.
How do you justify raising the fee on old equipment?
Because we hadn't raised it in a while.
But my equipment is getting older and less valuable
Oh, is your modem broken? Do you want a new one?
No! I just want to know how you justify raising the rates on equipment that is unchanged on service that is unchanged. You raised your rate and provided no additional benefit to me and your costs actually went down.
Because we hadn't raised it in a while.
That's when I left.
