Bank Of Baroda — refund not processed till yet now

I ordered a phone from amazon nd due to some reason i cancelled it and amazon initiated the money on 4th march with refund reference number # 6uhqsti50000k6rkmjo9. But till now it will not credited in my account. The time period of refunding money from amazon is 3-5 working days. But bank told me that it's refunding time period is 14 working days so now it left but my money is not credited in my account. And now bank want to take more time. I talked to customer service but they said me they take more time. My amount is large for me so please take action
