one similer case in buying a car from Pakwheels ad.
once there is a car CITY 1998, Khi registered, Bottle Green color, approx 90K driven. called him about the car, he said i will sale the car in 5 lacs, so i manage my cousins to come and inspect the car, the car was in good shape only a bit of work to be done, so after bargaining it was agreed on 480 Lacs. next day we request him to bring the file with him, so that it will be tellied with engine and chasis number and papers as well. so file was ok and i paid him Rs 3000 as bayana. before giving him bayana i told him that i will pay u the amount in 3 days, he said OK, next day he informed me to give the payorder today or very next day, i said we have commited to 3 days, he said my uncle want money as car is in his name. then when i arrange money he said i have sold the car to other person, etc etc, soo many kahanias. so i asked him to return my Bayana Rs.3000, he said why should i return as "U broke the deal" i said u broke and sold the car to other person. anyways after soo many calls he return me only Rs.2000 by saying i dont have money. He came to give me my bayana back in New 2010 Corolla GLI and lives in defence Karachi.
Anyways, these kind of people also exists in our country as well.
May Allah give them Hidayat.
