Canara Bank — i'm complaining about the refund made by amazon.in which is not reflected in my bank account

Address:

Canara Bank, Vyalikaval, Bangalore 560003

Sir/madam i had charged from amazon prime video, for free trail and even before the end of free trade about 81.42 ruppes and 1023.08 respectively.
I contacted them, mailed them and they called me took information about my issue and they intiated the refund of about 12.99$, and informed about 3-5days for refund, but it didn't reflected in my bank account, and again i called them they checked the status of refund and said that the amount was refunded and bank might held the money, when i contacted the bank service there service was bad, and said no refund is held and even i mailed them.

I'm posting some mails from amazon.in below

Your prime membership has been cancelled.
Dear chitra,

As you requested, we've canceled your amazon prime membership.

Since you have not used your amazon prime benefits, we are refunding you $12.99 which includes the full membership fee and any applicable fees and taxes. Your refund should be processed within the next 3-5 business days and will appear as a credit on your card's next billing statement. If your latest membership charge is still processing, we'll issue the refund as soon as the charge is completed.

If you'd like to join amazon prime again, start a paid membership by visiting the amazon prime page.

Thank you,
