Skills-ent.com - Not giving wages for my work

Hi Team,
I have worked for this company around more than one month for their company e-mail outlook integration and new website development without prepayment. I have already told them i will try my level best to complete their work on time because work is high. Also i have worked for them their organisation E-mail integration but they didn't gave me even single rupee for my work.They really hurts me by not providing my wages for the time i have spent my time to full-fill their satisfactions. They are trying to cheat me. Please ask them to provide my wages. They really sucks my blood for that one month to get it complete their work. Now they have changed their passwords of their domains and hosting without my knowledge.

Regards,
Karthik S
