How to deal with the online goods sell cheating ?

I went to a website called locanto.com and then I saw an advertise about Apple Macbook, I sent a message to the seller and then he told me to contact on his person mobile number, The mobile number was of USA or Canada as it was starting with (+1). I contacted him then he sent me a link of his website where I put an order and he was using a name of a famous store of Chicago so I paid the amount. He had given me the bank details of his Indian account. I transferred the money into the account, total 55,000 INR and then he told me that he accidentally sent 3 piece of laptop instead of 1, So he told me you have to pay for total 3 laptops. I refused so he started threatening me that I won't give any of the laptop as Custom will seize the goods. I doubted him that no one will send 3 pieces accidentally and then I refused to pay the amount he was asking so finally when I dig up into this, I found out that he is using the name of a well known store and then I contacted them and told them everything now they are investigating into this. Now, what I can do further from my side legally, I have his bank information where I deposited the money
