What to do when someone complain a fir against you in a bike accident

I was caught drinking outside a shopping mall and police took me to the station and took my ID and made me sign some papers. I was told that I will be getting a call from them in a few days but I never received any. Now after 7 months the same police officer called me and asked to come meet him at the police station or he will send a summon for me. I was not making any nuisance outside the mall and the police never took me to hospital for MLC. My question is can police call after 7 months from the day of challan and send summon for me? Because he was sounding as if he is looking for bribe.

PAYTM FRAUD TRANSACTION

The complaint is about cheating worth Rs 20000. I have no idea what should i do. I am briefing the whole story. Please go through it and help me out. Its 3 years old story. A guy took Rs 35000 as consultancy charges for some job back then. But he couldn't get me job and also ran away with money. Somehow after searching for quite long i got to him and asked for refund. After so many attempts he agreed to refund me and asked for some time and account details for returning my money. I gave him my ICICI & HDFC account. But again he asked for SBI account because he didn't have other bank branches there. So i gave him my father's SBI account details. And as promised he deposited Rs 20000 to the SBI account and asked for some more time to return remaining. I agreed as he had returned more than half & i trusted him again. But i was surprised when i came to know that all those 3 account have been debit frozen by respective banks. I didn't understand anything so i contacted the banks. They told me that there is a complaint filed against these accounts for cheating for Rs 20000. The point is , that guy dumped someone from hyderabad posing as a mobile phone seller and took money from him in my father's account. So the guy who paid for mobile got nothing and he made a complaint against the transaction and my account got blocked. Somehow that guy also got my number from bank details and called me and told everything. It was obvious that i was the one who cheated him according to him. I didn't have any option. I begged him to take the complaint back and also returned his Rs20000 myself. But still that guy didn't do anything for it to be settled. I still have the deposit receipt copy of bank .Its been more than 3 years since then and those accounts are still frozen. And banks say they need instructions from police to activate the accounts. Biggest problem for me is that more than A lac rupees are stuck in those accounts collectively. That person tells me to come to hyderabad then only anything can be done. I was ready to go but my parents fear that and tell me not to go. I haven't heard anything from police also in 3 years. We are a middle-class family from Bihar. 1 lac is very big amount for us. We don't know what to do. I have already returned the amount for which the complaint was made. Please guide me what should i do to get it settled. Pls help.
