Bank Of Baroda — I am complaint against refund 990

I talk to amazon executive officer about my refund status... And he said your refund has been initiated by us on 26 july. Amazon has been initiated my refund but still i don't get my money back. I don't get any refund information from bob. Before of this transaction i placed another order and i got refund of that within 4 days.
Why it's being so late now...
Now bob customer service call not connected. And saying your refund has been credited to your account.. But i don't have any transaction like this with my account.
