He sent us qr code and asked us to scan and enter upi code through which my account got debited. He told us his account also got debited and to try this again. We this this again for rs. 2000 and same happened again than to reverse the transaction he sent us refund code to scan of rs. 4000 the same amount again got debited.in this way he took rs. 8000 in total. He tries to do this again but now we had understood his trick.

He had with him dc / cc swipe machine. He sent us pic of the swipe machine too to again fool us so that he can use the trick again to make the fraud. When i said i will not he started making promises on his indian army dress, family, god, etc. He started abusing and giving bad words when i denied him to make more such transactions.
