Union Public Service Commission [UPSC] — mismatch in the serial numbers of the question paper and omr sheet provided in the upsc examination

Sir I was alloted (029)Jawahar Vidya Mandir, HSL Colony, Shyamali, P.O.Doranda, Ranchi-834002(sub-centre-'B') as my UPSC examination centre.When we were given the OMR sheet and the question paper there was a mismatch in their serial numbers. As we all know that the serial number in both the papers(question paper and OMR sheet) should match each other.My fellow candidates also raised this question but the school authorities said that it is the guidelines o[censored]PSC to distribute the answer sheet(OMR sheet) only to the students present for the examination. As a result there was a mismatch in the serial numbers. But some of my friends who appeared in different examination centres didn't faced this problem of mismatch as the OMR sheet was provided to each and every allotted seat irrespective of the fact whether the candidate was present or absent.I was expecting my roll number in preliminary examination selection list but I was not selected. It is a serious matter concerning my career. So I would request to conduct a detailed enquiry in this matter.Also I would like to mention that there is gap of approximately 500 students roll numbers either before or after my roll number. There might be a possibility that the whole lot is disapproved due to mismatch in the serial numbers. Expecting a positive response from your side as this is a serious matter regarding my career. Thank you.
