Scammer got confused

One time my phone rang and on the other end it was a man pretending to be a old man said that my wife had told me to send you ₹3,000. He had sent me ₹30,000 saying it was a accident and told me to kindly give him the ₹27,000 back. It was true sent me the money but it was a human typed messsage. I disconnected the call knowing that it was a scam. So guys please be safe from these types of scammers and check from the loved one.
