Passport Office Delhi — delay in renewal of passport without reason.

Dear sir / ma'am, i have been following with passport officers but i am not getting any response and support from them. I had applied my passport on 24-11-17 but till date i have not received my renewed passport. First local psk hold my passport for 20 days without any reason and they pass my file when i visited them and ask reason for delay there was no answer by local dpo. Even after police verification its been now 8 days, passport is not printed and disptached. Refer attached mails.
