Mahindra And Mahindra — Xuv700 booking amount refund

I have booked xuv700 on October 7th 2021 from meridian moto mahindra Pathanamthitta showroom in kerala. Sales manager suggested us to gave the booking amount of rupees 21000 on October 6th 2021 so that they can book the xuv700 as the earliest on October 7th. The sales manager told as that we will get the delivery by December 2021 but we got the notification regarding delivery in December that the vehicle will be delivered on August 2022.So we decided to cancel the booking of xuv700 because of the long delivery period and I gave the cancelation request to sales manager along with bank details, the sales manager told as the booking amount will be refund after 14 days but the booking amount is not credited till today(11/01/2022). When we contact meridian moto mahindra they fool as every day that they will credit the amount today or tomorrow likewise. from the last week we visited the showroom three times and they are behaving the same way. Please accept this request and refund our booking amount we need the money for an urgent purpose.
