Money scam

I was cheated financially by a person named Sagar pulimamdi , who was ex employee of Axio (formerly known as Capital Float) has an office in Shyamala Towers, located at 136, Arcot Road, Saligramam, Chennai . Already i m going through mental agony due to the loss of money but i did not take legal actions to preserve my dignity of myself and my aged parents. In the meanwhile i called up a person named Sarath kumar( contact number - +91 70639 44504), working in the same office, to enquire about the fraud. I learnt that Sagar had taken money from few of his colleagues as well and absconded from office. They started asking me details of Sagar 's whereabouts and parents contact number . I denied to provide the same as i did not want to be source of information of someone involved in such a fraud.But sarath started circulating my number to his colleagues ( surabhi with contact no +91 93689 24822 and the main respondent- Kushal Chatterjee)and i started receiving blackmails and threats from these axio employees saying i am involved in this fraud along with sagar and blackmailed saying they are gonna file a case against me. Please be aware that i am totally innocent and also victim of the fraud. If they proceed legally and file case against me, it will defame our dignity. Kindly save me from this situation and the mental depression i am going through because of this. I seek help on preventing such defamations and false accusations. Kindly help me out
