Hireinglobal — Rejection of work with no proper reason

I have applied to hire in global by Registering with 550 Rs and I have received 20 page demo work which to be submitted after completion and as per the given details the accuracy parameter was 80% . So i carefully done the work and cross checked 3 times before submitting. After submission I have received mail as ASCII Validation without showing what is the error or where is the error. They are just giving reasons and taking away the work I did for granted with no payment. I have send reminder mails to give proper understanding about the errors but haven't replied yet. I want the registration fee back or the report showing errors. Iam 100% sure its accuracy is above 90% minimum. Please do something immediately.
