Amazon India — took without my say so

Address:

9323 charly hill ln, 38016

In early january i registered my kindle and amazon offered prime for a free 30 day trial period, i am not interested and deleted the email but no reminders were sent before they started taking money for a service i don't want and would like the amount of $14.22 refunded back to my checking account. It was taken out on the 31st of february and i just became aware of it.
