Scorpion Verification & Consultancy Pvt. Ltd. Janakpuri Delhi

am basically from Bangalore and wanted to check an information about the list of companies in Delhi who can help me with my 10+2 background verification from IGNOU-Delhi. I got the information of this so called company called Scorpion Verification & Consultancy Pvt Ltd, with its registered address being 401 ,janak puri and spoke with Pankaj and Rohit. Pankaj attended my call and said he will be able to do the verification and would want me to pay 1500 RS upfront and the balance 1500 RS after the work is done. We had a verbal agreement before the amount being paid( advance)that the work should be done in a week time considering the emergency and was accepted by Pankaj and Rohit ( who called me to followup). I paid the initial amount and until now I have not received the verification report. Now when I call them they dont answer my calls. I tried calling from other number and Pankaj said will not return the money, do whatever you can do ??? please beware of such cheaters
