Amazon — refund amount not received yet

Hey,

I cancelled a product from amazon on 7th october 2019.
On the 10th of october 2019, refund of rs. 16999/- has been proceded by amazon.
My product order number is[protected].
"the reference number of the refund is - 223616.
After 7 days, the refund has not been received yet.
I talked to customer care regarding my issues but they didn't help me.
Also, i visited the bank.
The bank is saying no amount has been received by them. So i need to file a"charge dispute" on them, to get the full details.
I need the bank to resolve this issue as soon as possible
