Central Bank Of India — reversal of amount

Address:

At kalamba post kasura ya badlapur dist akola.444109

On 3rd of july i loaded 500rs in my amazon pay balance from my debit card. But due to some genuine reason i cancel that transaction by contact with amazon support team. And according to them they reversed my amount in my account and said upto 8th of july amount will credit in your account but still amount is not credited.
Here is the refund reference number sent by amazon on my mail.
Refund reference # 30005401870185103586929.
I hope you will resolve my problem as soon as possible...
