Hyundai manufacturing wrong parts ???

Firstly-MY PARENTS ARE PENSIONERS!! How many companies out there exploit our senior citizens? One would assume that a simple part like a water pipe will be in stock at all times? It is not! It is not just not manufactured incorrectly in the Far East, it is also not communicated to the consumer. This is an International problem that needs to be communicated to all your dealers. Then: if you promise to revert back to ANY customer by close of business is that not what you do? My parents have been without a car since last week and Hyundai is not even suggesting a courtesy car to my parents whilst they source the part? What is wrong with you people? What are you treating people like this? I will take this further and go more public if I need to. It is NOT our fault if you don't have the past-is it?? I expect feedback with a feasible solution from you within the next 24hours-even less as I think your service delivery is terrible and unacceptable. DEAL WITH THIS !!!!!
