Empty promiise and bad service

Bad service and empty promise,, I brought customer who bought brand new Hyundai i20 and the sales person by the name of Willy mashele promised that every customer that will refer to him with successful purchase Hyundai will pay me R1000 for referral bt after i refered this guy to him who bought brand new Hyundai i20 he is running around doesn't want to pay me the referral fee. The way Hyundai constatial kloof doing business is very bad and unprofessional.
