Magnum technopro - Company did fraud

I got a call from someone named Varun from this company called Magnum Technopro. They said that I have to fill *** forms in * days and they will pay **,*** Rs for that and asked if I was interested no further information was given. I said yes and they asked for my signature and photograph. As I started filling their forms my account got blocked due to multiple logins, which was not the case as it was only second time that I logged in and when I called their customer service no response was given. Sometimes later I got a call from this no. **********. The person told me that I have to pay them *** Rs in order to get my account unblocked. When I told them that I do not want to work with them anymore and asked to cancel my deal with them, to which he replied that if I wanted to quit working with them I have to pay **** Rs as a service charge. I denied to pay that amount and now they have sent me a message stating that they have filed a court case against me in Rajkot, Gujarat. Before everything let me tell you that neither their company is a registered one nor they have a GST no.
