Zoomcar — My payment refund issue is not resolved by the company.

Dear team,
Kindly, help me to get my refund from zoomcar. Follwing are the details of payment I made during my zoom travelling.
1) Total refuelling done in car was for Rs. 4215.85/-
2) Total Refule charges paid through zoom app, is Rs.1560/-
So the total extra charge I paid is Rs. 5775.85/-
I would expect to get minimum refund of money Rs-4215.85/-
For a proof purpose i have attached bills abd screenshot of my payments.
In additional they are mailing me continuously that my outsanding is pending.
I have tried to contact zoom through customers service but no one answers me there infact it took an hours keeping me in wait to answer my phone.
Kindly resolve my issue as soon as possible.
Thank you
