Hey @Lokesh_Mittal, @Yash_Sisodia27 and @Rohit_Ranjan1 ,
As mentioned we have limited space at the event. We have been opening the waitlist and reaching out to registrants based on our open slots. If you haven’t received a confirmation email yet it means that we won’t be able to accommodate you, unfortunately. 
We will make sure we have a bigger venue for the next event and are able to accommodate everyone.
Very sorry for this time!
