correction in school leaving certificate

Thanx in advance, can anyone help me out. So the problem is in the "last school attended" box of my school leaving certificate in which after the name of the school the school authority had mistakenly written false address for eg it is like - st. Joseph school, maninagar instead they wrote st. Joseph school, ramnagar. What is the solution. I need to correct it. My graduation is over, when i knew about the mistake and approached the school for correction they reluctantly said there is nothing to worry no one is going to check that. Pls help!
