Magnum — fraud case

Hello this company calls me and said that u have the option to fill the form at home and give target to me that u have to complete form and when i started to fill the form i am unable to complete the target but i fill some form due to some reason and then they call me after a week and said u have to pay 4000 rs but it is not my fault as i am unaware about this and they give me warning also that court case will happen tomorrow i[censored] don't pay 4000 rs till today. But this is very much wrong... This is a fraud... I am a student how i pay that much amount and main thing is why😠😠
