Recovery Of Loan Given To Friend

I was student studying abroad in Belgium. In 2017, one of my colleague who was also staying in Belgium took around 1100 euros which corresponds to Rs 88000 in today's conversion rate. He promised to return back in two months. But soon after going back to India he disappeared, switched of his mobile phone, change his email account. I tried making several contacts but of no response. I called their parents but they denied that his son has taken money and now not responding to my calls. I gave him a loan as cash on two instalments (500 euro each). I have proof of bank transaction of withdrawal of money from ATM on due dates. He was smart to ask money only in cash. I have audio and email confirmations of money given and acknowledging about the same. I am helpless and badly want to get my hard-earned money back. I belong to a middle class family and saved money to support my studies abroad and family expenses. I feel cheated and seek legal help if any possible to recover the amount. Please help me if any lawyers can provide legal help/suggestions on this.
