Hi aspirant,
If you don't get any seat in CSAB special round, then the fee you submitted would be refunded in your bank account. Choice filling would start in a few weeks, so I would suggest you to keep checking the website https://csab.nic.in/CMS/Public/View.aspx?page=79 .
Below is the link for the detailed information of CSAB 2019.
