Zoom Car — Deposit amount not yet refunded

Hello,
I've booked car in zoom car on march 05/2020.
I've paid 3924 as deposit and they mentioned the same has been refunded. It's been 60+days still no refund showed up
I've contacted state bank too they don't see any refund from Zoom car. I've dropped mail multiple times regarding this almost 50to70 emails no one get back to me.
My booking id -JPS6N8M5V
