As per discussion, for buying the second hand car from quikr, i spoke with owner (He himself tells, i am army man), so i credited him rs 3, 120 to (Name: dinesh, account no:[protected], ifsc code: pytm0123456), after sending the amount, he told us on the way to home for test drive, when he is away from 50 km, he called us to credit some more amount, i denied for that, without giving the delivery, i said i will not pay, so he is pressuring us more to pay it. Please can you action against him?
