I was booked online shivneri bus ticket from msrtc on 17/06/17 from sangli to pune. But bus was breakdown at islampur hence sangli bus authorities canceled bus and ask passengers to purchase hirkani ticket in cash and ask to travel by hirkani. Which we have traveled. Authority told us that canceled ticket amount ₹ 667/-will be received within 1day in my account. Which i have received only ₹617/-. Means short amount of ₹ 50/- received in my account. Pls refund short amount of ₹50/- in my account immediately.
