Zestmoney — Refund not received yet

My Emi was Double Time Debited from my account
My due date is the 5th for which I have given Rs 3, 864.40. One of Emis manually paid on 5th Feb 2023 and it shows successful credit has reflected the dashboard on that time and on the same date i, e., 5th Feb 2023 the amount was auto debited in two parts by ZestMoney (Rs 2, 826.00 and Rs 1, 038.40)

If I approach Customer care, they are saying that it will get refunded in 5-7 business working days but it has been more than 10 days now and I haven't received my refund nor I am getting any proper update about it. Also, I have submitted my bank statement to ZestMoney, via email.

Over the phone, they said it will be refunded within a week but now it has been more than a week and they are delaying it. Also, they never respond properly or update even after calling them and asking them several times.
