Indian Army — Domlur army camp

Hi received a called from Satish Kumar 94BNBSF he said they need hearing test for 100 members and asked us to send quotation and asked us come the very next day for testing. We sent a quotation of 30000/- rupees and we received a call from them saying they don't have email id and asked to send the quotation in mobile what's app mobile number- [protected]
And he checked with us if he have phone pay so that he can directly transfer the money. He said he will do a video call and he will say what he needs to do while . On the video call he said it is army so we need to see how you will make a payment. He asked us to click on credit card payment and asked to enter 30000 and asked to enter our PIN. That's when we got to know they are fraud. Thank God we asked them why we should put our PIN and then they disconnect the call.
