Bigeagle Advance Service Private Limited - Typing project given but payment not done

I had taken a typing project from Bigeagle which was supposed to be completed within * days. I was in conversation with Ms. Alpana. I had also deposited a security of **** INR which had to be given back to me on successful completion of the project. The project was submitted by me in early April and they people told me that it is taking some time to get it checked and later stopped replying to my emails and messages. Three months later in July, when I contacted them again saying that I am going to take a legal action, they sent a report very next day stating that they have rejected my project. I suspect there is no business going on and their only business is to con people and take money from them.
