I reserved my seat in chandigarh university by paying 10000 and first they assured me if i get admission in delhi university or some other university they would return the money. They assured me give 9000 after the deduction of 1000. But now i cancelled my application form and when i took admission in some other college and contacted them for refund the rest 9000 they refused to give it. I want my money back.
