[Resolved]  Csr — fraud case

Last year on august i received a call from a company which at the time i didn't know was a fradulant one.
Upon finding out i immediately contacted the customer support and asked to cancel my registration, but they made me sign a fake document and now after so many months are threatening me that the case of section 420 has been filed in the court.
Please help me with this. I can share the number of the so called advocate if required.
