I would suggest take CSE in VIT-Vellore. I myself have taken a drop and I don't feel something huge will change. Trust me, CSE in VIT is quite good option considering you don't have any IIT options open. I hope this helps. If you still have any questions, comment below. I will be glad to help.

You must have got some papers from the college which has all the necessary details on how to get a refund. Please check them and if your problem isn't solved, comment below. I will be glad to help.
