how can i fix my daewoo fr 143wh fridge?

daewoo fr 143wh. Whilst trying to defrost the ice compartment of my fridge i thought it would be a clever idea to chip away at the ice to get rid of it more quickly.Because the ice was so thick,i have chipped into the metal part which holds in the gas.The gas has now been released.Can the fridge be reaired?Or can i still use it without the ice compartment?Can that be disconnected so that the fridge can still be used?
