As Casey said, you are stressing this snake but repeatedly offering food daily. Have a look over our caresheet. Describe your setup and your interactions with this snake in the time you've had it. Where did you get the snake from? Are you offering food in the form it's used to (mice or rats, live, f/t or p/k?)

These snakes are shy, nocturnal and easily stressed. They need a proper enclosure with temps and humidity in the correct ranges, a quiet environment and time to adjust to the stress of moving from one home to another. Most of the time refusing to eat is a symptom of a problem or set of problems - not really the problem in itself.
