I purchased one Hyundai i20 Magna CRDI with SPS HYUNDAI, Thiruvallur in the month of March 2013.During the time of booking I was promised for a xchange bonus of Rs.10000 by their executive and was cheated.Then got it back after 6 months by complaining Hyundai customer care(HMIL).
People from Hyundai regional office, Chennai helped me to get it back from SPS Hyundai, Thiruvalur.
