Lucknow RPO — delay in passport

My name is Kapil Gupta. I have visited PSK Kanpur on 2nd Dec 2019. All my documents had verified at PSK. Next day i got message that police verification has been initiated. Police visited to my home and all verification done. On 18 Dec 2019 Police has submitted clear report. After that there is no progress in passport it is showing Police Verification Report for passport application is under review at the Regional Passport Office. Passport will be dispatched after Police Verification Report is found clear. The applicant would receive an sms/e-mail once the passport is dispatched. Till now i did not get any update from Passport office. Even i tried to reach Lucknow RPO but could not. I continuously tried 4 hours to contact it says every time number is busy.
When i got tired then i contacted to Passport office number customer care they told me you have to visit RPO but problem is i am living in noida i can not go to lucknow frequently.
