This symptom (if the bowl is not filling completely) sounds like the refill tube inside the tank is not inserted into the overflow tube, or is missing. This small tube is usually near the fill valve inside the tank. If the tank is not refilling this sounds like the fill valve is clogged or faulty. Best is to contact a plumber to replace this valve.
