Bank Of Baroda — amount has not been refunded by the bank

I have ordered for an electronic appliances from amazon.com which after receiving it i didn't like it for some reason and then i had to return it. And i got a mail that they had refunded it to my bank account, but i didn't get any refund amount in my account from the bank. I have tried talking to the bank staff but they didn't respond me. I should have been receiving the amount before 2 months but i haven't received the amount from the bank.
