Hyundai Motor India — gm is not providing my money back

Address:

Deoghar, Jharkhand, 814112

Showroom name: Baidyanath automobile
Gm(General manager) name: Indrajeet chodhri .

I was planning to take a vehicle from this show room and i paid 11k advanced but due to old model i change my plan to not take this vehicle after that many times i called to the Gm of this show room and he is telling all the time tomorrow or day after tomorrow i will pay you and this thing is happening from the last one month .

He don't have sense to how to communicate with the customer and he is abusing also if i am asking my money back .
