Amazon — Amazon company audible.com illegally making transactions from saved credit card

Address:	400068
Website:	amazon.in

I had a debit card and a credit card saved on my Amazon account. Suddenly I received an alerts that 15$ was spent from my account. I could not trace the source but later again another 15$ were spent from my other card at a similar time of the day. I noticed that it was through some company audible. And then eventually after doing some research I found that it was an amazon company and the link between my two cards was my amazon account.
This is an absolutely illegal way of extracting money from the saved cards without permission. I will ensure that the message is spread to not use amazon services.
I want amazon to acknowledge this and ensure it doesnt repeat with any other customer and secondly I want amazon to reimburse me for the hassle I took to block and reissue my cards at 12:00 am in the night to ensure that no further fraud happens on my cards.
