Scam in rapido

I drive rapido bike taxi as part time. Today at 11am I got a trip near me in Royapettah. Accepted the ride and then reached the pickup location and couldn't find the customer so I called him. Call full ring pochu but the customer didn't pickup the call. The customer then gave me some other number in the chat to call. Called the customer i could find out he's a north Indian with his accent. He told me to wait in the pickup location for 2min and suddenly during that call i got a message stating "account credited 3500" he asked me in the call "did u receive 3500 rupees sir?" Checked my bank statement but 3500 wasn't added. Then I took a closer look at that message which i have recieved then only I got to know that it's a fake message which was received from that customer number and not from my bank. I could smell the next step he would do, he's gonna ask me "3500 rs I've sent you by mistake, please send it back".So I told that customer "yes Bhai 3500 credited just come to Royapettah police station and collect the money". Then immediately that scammer cancelled the ride. Just be alert people and fellow drivers on ola, uber, rapido or anything if you receive any message stating your account credited money, check in that message whether your last 4 numbers matches your bank account number. Also check the sender is it by bank or a random number, sms from bank will look like JD-UNIONB or VA-UNIONB or something similar like this. Also if anyone has really sent you money by mistake, it's always recommended to go to your nearest police station and then do the transaction of money infront of police. I don't know any legal steps for this if anyone has any idea kindly drop them also.
