Money scam

My neighbour was doing trading business by giving 5% profit share every quarter. I also joined as one.of his clients by investing 5L for which i was getting my profit share every quarter. Later he approached me to ask if I wud join with him as a partner where in he would take care of the technical part n I would get the fund for him. Since him being my neighbour and the trust tat was built in few years I agreed and got around 65 lakhs of fund. Initial one year he was giving the profit share and used to share his bank statement every month to me by sending screenshots of his statement in watsapp. There by gaining my trust of the capital being safe. After one year I got to know he was not trading but was giving the profit share from the fund tat I have got in. So I asked him to return my entire amount. He asked for sometime and after six months he said he has lost all the money. When I checked on the bank statement he was sending me every month which showed 65Lakhs , he admitted that he has edited the statement. His parents approached me and promised to return all my funds. However, they returned only 20 lakhs and balance 45 is pending. It's been 8 months now and they are reluctant to give the balance amount. I have all the call recordings and proofs of the edited statements too. On a humanitarian consideration I dint approach the police. but I am now helpless, kindly advise
