Usys Services — cheating people

Sir,
I saw an ad somewhere about this company and contacted them.. They gave me work with 3000 forms for 15 days on oct 24th.. Upto 2800 forms is accuracy... I failed to submit within 15 days becoz of some health problem.. So they asked me to pay rs.7800 so that they can extend time.. Am unable to pay.. But at last paid them somehow.. They gave extension upto nov 5th.. Then i submitted my work within time.. But they gave me fail report with 2681 pass forms.. I checked the report but i found 155 of them were correctly submitted.. I didn't gave double spaces in work.. But they were saying that i gave double spaces.. I asked them to check... I sent those images to them.. They said they manually check and revert me back within 72 hours.. Today they are saying same 2681 is your pass forms... They said we checked that u gave double spaces... But i didn't gave double spaces... Please help me they are cheating... Please help me to get my 7800 back... Am a student and thought that work will help me out of my problems.. So i paid them.. Please help me.. I saw that u resolved complaints came from people complaining about usys services.. Please help me to get my money back
