False 420

Multiple orders got placed from my account on an e-commerce website worth Rs 700. Immediately I called the customer care of that website and informed that "Your website has been compromised and multiple orders are getting placed from my account and I have no knowledge of the same. But they took no action on that.". Post this to my surprise these orders got delivered to me worth approx 700. I forgot this thing and months later police official came to my office and told me an arbitrary FIR was filed by a person in UP(Uttar Pradesh) for loss 27k via fraud transaction from his account and out of that 3 is linked to my e-commerce website. He took my signature on FIR and some court format which says"You are accused of 420 case is being filled on you but nothing will be done if you follow this n this and present before the court whenever asked(All this in Hindi like normal format nothing wrong)" I told them I have nothing to do with it. Post this I have emailed many times about this to that e-commerce website and returned those products. Also, I had sent many written letters to their various departments but no action was taken. My family person was trying to help told me that a few days back police has filed the charge sheet and my name is on it. What should I do? I have done nothing wrong. Please help.
