Olx — Car/

I was fooled today by a fraudster and he looted 4200₹ .From an ad that was posted in OLX for Mahindra Thar CRDE 2015.It was quoted at an attractive price 3 L. When I called the Number[protected] that was in the ad. the person claimed he was an Indian army personnel CISF and he shared his ID in the name of Rajesh Kumar Meena also his name and photo in true caller was matching his CISF I'd and he sent his photo with uniform that had his badge name as Rajesh Kumar Meena so I trusted him completely. This guy said he works in Bangalore airport as CISF and in order to inspect the vehicle he said he would send it to Palakkad where I live through the airport consignment service thst was enroute to the kochi airport .
He said in order to do the booking via the airport military service I need to send him 4200₹. And 2500 would be refunded regardless I take the vehicle or not. I live in Palakkad and would have costed me around 2K to travel to Bangalore and was alright if only 2500 was refundable so i sent him the cash to the below bank details.
Name: Gurdeep Kauri
A/C : [protected]
IFSC : FDRL0007777
Bank : Federal Bank

After which he sent me a challan which looked absolutely fake and immediately I knew I was fooled and was embarrassed and felt ashamed .The next day morning some one else calls me in the name of Parveen kumar[protected] and claimed he was the airport consignment service guy and thst he confronted a problem on the way in Coimbatore and wanted me to transfer 11200 without which he cannot bring the vehicle to me to inspect.
Now when I said I am not interested to take the vehicle he said he would not refund nothing and he stopped responding to my calls or messages.
I'm not sure how in this earth I slipped to this fraudster. The thought of being fooled keeps haunting me.these fraudsters have sketched their every move very well thst makes you believe completely. Please be aware.
I am attaching the pics that was sent to me
