In nearly all Federal agencies, fees collected by the agency do not go back to the agency that collected them. Those fees, taxes, fines, etc go directly to the US General Fund, where Congress can do whatever they want them.
So, the idea that FCC is collecting fees to offset their expenses doesn't make sense.
FCC is just doing what Congress is telling them to do. Write your Senators and Representatives and tell them the idea doesn't make sense because the funds will not be available to FCC unless Congress appropriates it. FCC is an agency funded by appropriations. There are a few agencies funded by user fees, and FCC isn't one of them.
