My water dispencer supply hose

I have broken the supply hose that goes into the freezer door through the hinge.They say they do not have a replacement.They say you have to replace the whole door.The door cost $500 That seems alittle extreme.Does anyone know how to fix this issue without buying a door.Its a $2 plastic hose for gods sake.I am even thinking about cutting a hole on the inside of the door,repairing the hose then patching the hole.I don’t know if that is the right path
