Nissan Motors — Non Refund of Booking Amount for Magnite

Address:

Etco Nissan, Vidyavihar West, Mumbai

I had booked Magnite with Etco Nissan Motors Vidyavihar West, Mumbai in Feb 2021 after being given assurance that if Booking cancellation is done, l would receive ENTIRE REFUND WITHIN 7 Working Days without any Cancellation.
I cancelled the booking as waiting period was too long. Now it's More than 3 weeks After Cancellation BUT still no Sign Of Refund and they are using My Booking amount Interest Free
