In our dive into r/ProRevenge for today, we hear about someone who put a car up for sale and a potential buyer bailed on the sale and canceled the deposit check. The seller had turned down numerous other potential buyers because the deposit was made and now the seller will be out the deposit money and not have sold the car. OP and his friend, who is trying to sell the car, weren't going to let this jerk get away with lying and canceling payment on the deposit check, so they set up a prank call program for him to receive his cold revenge from.
