Not Happy with After sale service

I bought Santa FE automatic less than one year back, of which for more than last 2 months it has been at their service center. For a minor repair job my car is stuck there and the worst thing is that for last 50 days i have been calling up daily, writing mails to who so ever possible but these people refuse to respond or tell me the status. Initially they had fooled me by saying that it is a matter of 2-3 days only but subsequently they changed their stance. For last 45 days all that I hear is that they will get back back as and when they have a clarity which it seems they never seem to get. I have been completely harassed by Hyundai company and their service center people (Hyundai Motor Plaza) and the experience is horrendous. NEVER BUY ANY HYUNDAI PRODUCT, THEY TREAT THEIR CUSTOMERS LIKE SHIT. THEY MAKE YOU FEEL LIKE A BEGGAR.
