Indian Bank — money not refunded #money was kept on hold by the bank

Address:

West Godavari, Andhra Pradesh, 534235

I’ve requested for refund on an amazon product. From their end they processed the refund successfully and shared the Refund reference(RR) number also. But the bank customer care are not able to solve this issue. They are intentionally not considering my issue. They are asking UTR number. But amazon people shared me RR number (it will be generated upon successful transaction). It is bank gateway problem only. With this Indian bank, I’m being troubled 2nd time, with these refund things. So, I’m charging a file dispute regarding this on Indian bank.
