Volercars — payment didn't refund

Address:

Jamia Nagar, Okhla, New Delhi, Delhi, 110025

I booked a car on 14th June 2019 at 7:35 pm for outing and paid 9255 rupees advance payment, they give time slot for recieving car on 14th june 2019 at 11:00 pm, but they canceled my booking due to unavailability of car. So they give me 10 days of time for returning my money back in my bank account but today is 6th of august and approximate 54 days has gone and their customer care executive giving a new statement all the time when i call them. So now I am totally embarressed and now dont know what should I do in this case.
