Capgemini — Complaint on interviewer

I have attended an interview recently conducted by capgemini online and the interview went well like the scheduled time is 30min and interview went about 28 minutes. After the interview was done I got a call from interviewer from a landline number and he assured me that he is the one who took interview to me and i recognized his voice then he asked me to pay the money so that he'll give the positive feedback if I don't pay the money of 1 lakh he won't give the positive feedback. His name is
"Venkata Subramanya Murali Krishna Ravinuthala", Kindly take a strict action against him and review the interviews he took on 4th and 5th of FEB. Please select the candidates who performed well.
