The washer in the shut off valve has probably split or come off completely over time.
if you have water to the rest of the house and its the toilets only then either someone has turned off the valves under the toilets or the fill valves have both failed at the same time. [not very likely!!] cant be much of anything else.
The valves arent shutting off and must be replaced.
Valves under the sink NO WORK HUH?
A valve in a plumbing line that closes the line before the fixture it is connected to. For water there are usually shut off valves under the sink and right above the floor for the toilet. For gas, there is usually a valve that a flexible line attaches to and then to the appliance.
depending on what type of faucet you have sometimes you need to close both hot and cold angle stop valves under sink.
Venous blood is under very little pressure, so the valves prevent the blood from flowing the wrong way. Arterial blood is under pressure from the heart, so it does not need valves.
pull the toilet. Make sure the trap is clear on the toilet, and then snake the toilet line.

valves are not present in arteries because in arteries there is high blood pressure
