Passport Office Delhi — passport/error in name spelling

Address:	Gurgaon, Haryana, 122001
Website:	passportindia.gov.in

I have recently taken passport office services to make passport of my parents.
I stay in gurgaon and i went to passport seva kendra in udyog vihar to avail the services.
I started with all the formality completion for my father's passport mr. Jai prakash yadav as per the guidelines mentioned by the passport seva kendra officials. At the last stage of passport formalities, one of official made a spelling error in my father's name and did not show the final changes made (As were shown by the previous officials). The name of my father in passport is now jai p'ar'kash yadav instead of jai p'ra'kash yadav which was required. I tried to login again to the passport sewa site and take an appointment for name change but it is not going further without paying a sum of 1500 rs. I don't want to pay the same amount again just because one official made a spelling error in the passport of my father.
Please help in the above query and suggest what can be done in this case.
Thanks
