TCS iON — complaint against tcs ion digital zone amritsar

Sir my rbi assistant exam was held at tcs ion digital zone amritsar on dated 15.02.2020. But the tcs ion digital zone amritsar did not allow me to sit in the exam just because my surname was not mentioned in my admit card. I also shown them my others identity proofs like my voter id, driving licence but still they did not allow me to sit in the exam. My photograph was also there on my admit card but they didn't allow me to sit in the exam and because of them i have lost my valuable opportunity. I did not have any problem if they ruined my opportunity for any other reason but just beause of a surname was not mentioned they did not allow me to sit was wrong.
Kindly sir look into the matter to restore my lost opportunity
