Amazon India — Renewal of amazon prime membership of 10.99$ (737.43 inr) without my consent illegally!

Address:	400094
Website:	Amazon.in

Hi sir,
This is regarding the transaction of 737.43 inr ( of 10.99 $) made by Amazon.in without my consent using the saved details of my credit card for renewal of my Amazon prime membership, which I never asked for. Its totally unacceptable to me. Kindly cancel this illegal transaction & revert the money back.
Amazon is looting the consumers by first giving free trial membership of 1 month. After the trial period is over, they, On their Own, without the knowledge of the customer, shamelessly renewing the membership on their own ILLEGALLY using the saved Credit Card details of poor consumers on their site. They sent a sms to me indicating, they have deducted the money from my credit card for renewal of my amazon prime membership, and for which further authentication (like sending an OTP to consumer etc) is not mandatory as per RBI guidelines! This membership is amounting to 10.99$ or 737.43 INR even without my knowledge and consent.
Such a fraud on part of Amazon India!!!
Please help me in getting my money back.
