Driving License — driving license issue

Hi team,

My father has applied for driving licence renewal in the month of january whose detailed is mentioned as below:

ø name: krishna kumar saxena

ø application no:[protected]

ø date of renewal:15bfeb'19

It was advised by rto team dealer that it will be delivered to the address that has provided on the documents but nothing happened such.

He is a senior citizen person and can’t chase rto office in this scenario where every formality has been completed from his end.

Could you please take a look and advise where it is stuck and how long it will take to deliver o the address provided?
