Agreement and refund

I enroll myself in company that give work from home opportunity. There were asking me from money as a service charge, banking charge, agreement charge, couriers charges etc..they never told total money once they always asking money divided from first they ask for service charge than they ask for agreement charge and so on. And about Agreement I never sign that agreement and when I asked them for Agreement that I want to see it they ask after I complete my 3 project they will give..and I trusted them after paying about 36k I total them that I want to cancel that agreement becoz once I said them that I don't have money so I can't pay it they say If you don't pay that charge Legal notice will come to your house. So because of that I paid them upto 36k. After that I said I want to cancel my agreement so they say pay 8k we will cancel your agreement. After paying 8k I ask them for refund all that agreement charge m, service charges etc which they told that Is refundable. So for that they said according to court refund law you need to pay 2550 rs to get your refund...In all this I lost total 44k ... So what to do now? Did that court refund penalty is really exist? Is this company is really legal they did not show me any agreement as they take agreement charge for me..what to do now?? Plz help
