Drivezy — Not refunded

I booked a car for 8.5k in month of December 2020. And they canceled the ride due to car unavailability.

Now it is July 2021 and i have not got the refund yet. Everytime i call, i email, they just say kindly wait for few more days and its been 8months not recieved my refund amount.
It is very unethical to keep someone's money like that. Always they say refund is happening in batch. If they don't have money to refund then why are they still running the business and cheating ppl.
