The only solution I see is to wait till the end of July .
If you dont receive it or get it approved by then then go to delhi find a PG to stay and then keep visiting their office everyday to pester them to issue your license
Something must be holding up since those who applied after you have gotten it issued . They just might be too lazy to update it on their website
If you dont want to wait any longer then go to delhi and to the DGCA office as soon as possible
Visiting time is between 4-5 pm and expect to meet plenty of CPL holders hanging around waiting to sort their problems
