Andhra University — Mistake in certificate without my fault

Address:	Visakhapatnam, Andhra Pradesh, 530003
Website:	www.andhrauniversity.edu.in

I have completed my b.com in march, 2014.In my od, medium is printed as 'telugu' instead of 'english'. It is very important to correct the medium as it affects my career.In order to make correction, i have called up the university and it has asked me to pay the amount of rs.800/-. But why should i pay money for the correction in certificate even if the mistake was not due to my fault? Please consider my complaint and clarify my query giving justice to me.
