Kamara Techno — Threatening for money

Respected Sir/Ma'am,
I wanted to complain about this company named KAMARA TECHNO which is located in Gujarat.
Few days back I received a call from them and told me they won't ask any money from me and beacuse of this lockdown issues I needed money and I said yes to them. My report was generated and there were many places where I wasn't wrong but yet they spelt it wrong . Now their advocate named Harish is asking me for money and threating me to pay the amount otherwise he will file a case on me. Please suggest me to what to do. And I mailed you today only please suggest me something as I am very tensed
