Friendship Club — fake and threatening calls

I was told that Rs 1500 is required for registration for jobs and later on I was told that I need to spend time with girls and have to pay the hotel fees. I immediately denied and since then I am receiving calls from various numbers claiming that they are from police department and need to pay more money. I am helpless now as I am from a lower middle class family and wanted to get a good job which turned out to be a nightmare. Please help.I can provide the numbers if required.
