dont worry..the same happenned to me a cupl of months back..you just have to go back to immigration dept and tell the officer(who gives the token on the first floor) to check your application status as its says postponed online..he will then check there itself and tell you the reason..(in my case it was a document missing-as they didnt ask for it at the time of application..)in your case it may be the same,esp since you already had a interview and then its status is changed from rejected to postponed..dont .worry,n waste time asking for answers here,go to immigration.first floor-officer who gives the tokens(outside the hall where the applications were submitted..
