Business ploy by BP

The con run by Pick & Pay and BP. Fill up with R500 four times and collect a toy car. Since the beginning of June there has been no cars delivered to the outlets, but they keep promising stock every week, so we just keep putting in their petrol and keep collecting codes for our free cars. Now the promotion is running at an end, there are still no cars, BUT they now insist that there will be limited stock, so first come, first serve. Very EASY, let everyone collect codes after putting in fuel and then deliver a few cars and "SORRY" to the rest. Surely they know how many cars are outstanding and supply their customers with the cars promised by the promotion.
