Rishton Ka Sansar — Fraud

I have registered a membership and at the time of registering they told me that many of the profiles are interested in yours but now they are saying that they lost all the data related to me or my profile. Now I want to cancel my registration from that company so they told me that it is not possible. But according to company terms and conditions that they will return 50% of registration amount which is also mention in his website in Terms and Conditions I want to complaint against Mr Shubham Jaiswal and Mr Sharmaji(In A/c department).
