Renault — Car deallocated from my name and no refund

I have booked Renault kwid vehicle at ARKA Renault showroom by paying booking amount . And waited for more than a month.
Yesterday sales person sent one more quotation saying that the car booked by me is allocated to someone else who is ready to pay immediately and I need to book car again. I wanted to escalate this issue. Sales person Satya from ARKA Begumpet was given all wrong promises. Now I don't any clue what to do except proceeding legally.

This is initial intimation to you before proceeding further legally in this.
might use this email as a legal evidence for futher processing.

Looking forward for your reply.

Surprisingly these guys are not providing any refund as well till date.

Thank you,
Sasikiran
