VTU, SBI and My result

SBI is the largest bank in India. Pay package for an entry level officer in SBI is double than the average CTC of an entry level engineer graduate. The company in which I got placed told me that it will pay Rs 2,75,000 per year, where here it was Rs 5,40,000 per year. In July, SBI called for application for exam for various officer posts on probationary basis. When I applied in Aug 2008 I was not aware of these facts. As I am always interested in competitive exams made an application. At that time I was clueless about the economic situation of today too.
It was not tough, I could easily clear both SBI prelims and main exams held in Oct and Nov 2008. I got result of main exam in January. The world already started experiencing a hard time. Thousands of job cuts are being reported from all over the world. It was my second anniversary of Campus placement, joining date was not intimated by the company. So I was happy that I could go to SBI and beat the effect of economic recession or also you can term it as depression on me. But the fate was different.
I went to SBI headquarters in Bangalore on 9 Feb 2008. As it had been mentioned in the advertisement of SBI recruitment cell, a person who has finished his graduation on or before 1 July 2008 was only eligible to apply. I had finished my graduation in the month June 2008. Though VTU had provided me the marks sheet tells I passed the exam in July 2008. There started a conflict. On which date I became a graduate? But the officers were not ready to accept my application is valid because there is no proof to confirm I became graduate on or before 1 July 2008. I had completed my last exam in June 2008, if my university VTU had printed the fact that "he has passed the examination held in June 2008" I had no problem. But they did not.
Look at the pictures. First tme table- clearly tells exams were over in June 2008, but certificate read "held in July 2008". A small neglect of VTU made me pay a heavy loss. I was sure that I will get this job, as my performance through out the examination procedures was good , if this mistake from the VTU was not there in my certificate.
Later a question aroused. From when should a student considered as a graduate? Is it on the day when he gets result? or from the day when he writes the last exam? or the day when the university delivers convocation certificate? When it was discussed with the educationalists and some high court attorneys they made clear that a student becomes a graduate from the day when he writes the last exam. Result tells whether he became a graduate or not from that day. But now, whom should I blame for this? University- VTU- which did not provide the fact that I passed the exam in June 2008, or SBI- not willing to accept my application because I don't have a proof that I had not been a graduate on 1 July or my result itself?
