Passport Office Jaipur — Over Delay in issuance of passport..now over 5 months

My file number is JPC[protected]
I had my scheduled appointment for my passport on the 12th August 2023, following which my PCC was also cleared.
5 days later I recieved an objection on ECNR.
Did not understand why I recieved it as no additional documents were asked during the scheduled appointment.
All my certificates were in order, my 10th and 12th certificates were provided which is from an IB board (International Barraculate) as I studied from Pune.
All documents pertaining to education were self attested as per col.2.15 under section B of the manual and sent by speed post.
On a number of occasion I have contacted the customer care office who have confirmed the reciept of documents..but till date it is showing under review.
Do not know how to proceed further...as there is no clarity... kindly assist.
