What happens if a player says 'call' but throws in enough chips to raise?

How to use this answer

This answer is based on the mathematical principle or published rule identified in the source below. If the question involves a live betting market, confirm its settlement definition before applying it to a specific bet.

Verbal action commonly controls; the extra chips are returned unless clear prior rules or circumstances establish a raise.

Tournament rules are a useful reference, but a home game or cash game can have different house rules. Make the chip amounts, action sequence and card visibility clear before deciding a disputed hand.
