Central Bank Of India — refund is not been credited yet

Address:

Bhilwara, Rajasthan, 311001

I was getting the refund of Rs 10995 into my bank account for one of my order i ordered from Flipkart.
The refund was initiated from seller side on 4th march 2020 itself and they told me that it’ll take 8 business days to get reflect into your account.
But it’s already been 12 days and till now also I haven’t got my refund back into my bank account.
I had even shared the reference number that is "74766510064009305468002” but still haven’t got any answers to my problems.
