Honda Cars India Ltd. — not received refund of advance payment

Address:

D 2/9, Bareipalli, Industrial Estate, Ainthapali, Sambalpur, Sambalpur, Odisha, 768006

I had booked a honda wrv on 23rd march 2018 and made a payment for the advance booking of the vehicle on the same date but due to some reasons i did not buy the vehicle but demanded a refund.
I have complained several times to the dealer and they asked me to file a complaint
An application was given along with my bank account details as they said that they would refund the amount.
Till date i have not received the refund as its already more than a year.
