What should I do next? I have been issued notice under 91 Cr.PC by Inspector of Police,kulsumbura?

I have been asked to produce my identity, address documents with all the relevant documents related to a specific bank transaction within next 7 days from the date of notice receipt (on 11.04.2023) by Inspector of Police, kulsumpura PS, Hyderabad, Telungana. I learnt about FIR has been filed on me under section 419, 420 of IPC, and sec 66 D of IT Act. This transaction related to crypto currency trading in binance exchange market place.. My counterparty/ buyer had placed buy order of Rs.70000/- on 06.02.2023 and sent me payment to my bank. After payment confirmation in my bank, I released his crypto to his binance account wallet instantly, he even confirmed me the receipt of his crypto with thanks in binance application chat. After few days he filed a chargeback application to reverse of Rs.70000/- in his bank saying fake reason as he has made payment by mistake to me instead to someone, even after receiving his equivalent value (buy order) of Crypto currency in his binance wallet. My bank initially held amount Rs.70000/- in my account, I submitted all the documents with detailed explanation alongwith binance exchange certificate of order completion related to this transaction in person & through mail to my bank; they forwarded these details to remitter bank(buyer bank) and after about 25 days, they accepted my explanation & given documents and released the held amount Rs.70000 fully. I withdrew some amount later, my bank ac balance was Rs.40213. Now, my counterparty has filed complaint & registered FIR on me with false & cheating motivation; Telungana Police Dept served this notice under 91 CrPC through my bank on 11.04.2023, hence, my bank again held Rs.70000/- again, now my ac bank balance showing Rs -29,787 ( in negative)., And now I have been asked to appear with the documents in person at the kulsumpura police Station, Hyderabad. What should I do now? Should I appear in person at the police station (with or without advocate) within next 7 days? Will they arrest me if I appear at the police station now? Or will they come to my home for arrest in future without any notice? Are these sections bailable? Or non-bailable? Do I need any precautions? What should I do next? How can I prove my side of truth? How I can save and secure my hard earned money which I invested in crypto market last year? Can I file Counter- Complaint/ FIR on my counterpart/ buyer? how to file my complaint? I have all documents related to this transactions with me, except 2 other important mail correspondence which were received by my bank from remitter( buyer) bank, My bank refused to share to me stating those are their inter-bank correspondences, how I can get it from my bank? I am living with 3 kids who are under 4 year now, my family members are very much worried about this. Please help & guide me..
