State Bank Of India [SBI] — Not credit money to the bank account

Address:

Berhampore ADB (003914)

Sir, I bought an electronics thing from Amazon and applied for a refund by returning it for a reason. Amazon picked it up on 12th September and returned the money(Rs.399) to the bank on 13th September. But till today my money has not been credited to the state bank of India. Later when they contacted the bank with the reference number from amazon, they refused to help. That is why I am appealing to you. Amazon says they have nothing else to do. Please help me to credit my money to my bank account.
