Hyundai Motor India — Cancellation of booking - booking amount not refunded by dealer

Address:

Sai Auto Hyundai, Saki Vihar Road, Mumbai

I had booked i20 Nline with Sai Auto Hyundai Saki Vihar Road, Chandivali, Mumbai. Had paid 10000₹ for booking. Due to some personal reasons, I decided to cancel booking within a week. Now dealer is not refunding my amount and sales executive - Mr Karan S, not taking my calls too. No reply from Hyundai Customer Support nor Dealership even after repeated emails.
I was not given any documents while booking nor was I informed regarding cancellation fee. This is pure cheating by this dealership.

Please do not buy any car from this dealership, they are frauds and have no regards for customers.
