Amazon India — amazon pay - i have totally getting humiliated by the amazons response...

Dear people,
I have lend a loan from a company called zest money to buy a motorola one power in flipkart, by mistake i have been generated a amazon pay voucher. It was an accident and i totally agree with it. But after i received my mail from zest money i have two links with the vouchers value of 10, 000 and 5, 999 respectively.
With more of a curiosity and eagerness to buy the mobile phone, i have clicked the link in the mail which i have received from zest money. The amazon app automatically opened and without my authorisation the voucher has been redeemed. I have got amused and to reconfirm it, i have clicked another link and it has been redeemed automatically. So i strongly now believe that the amazon app have redeemed the vouchers without my authorisation (In all my calls i have recorded it but none of the executives where answered it). I consider this as illegal and a crime, because it is a money transaction it should have asked for my authorisation.
I totally see this as ethically wrong, and i have called the amazon customer care and have spent the whole day with the disappointments with the amazon customer care.in case of doubting my words kindly listen to all my call recordings and you should have aware that what have actually happened to me in detail. Also some of your customer care executives were very rude to me and some of them were very sarcastic and some were totally humiliated me.
Then i believe in your ceo’s jeff and amit and i was marked them in my mails, but still no solution were received end of the day. This have made me very disappointed and also made me regret that i have been doing business with amazon all these days. I have literally felt ashamed at last for being with amazon. Also some people claimed to be the highest level of escalation have called me and listened to all my disappointments and took two more days and again replying through email with same disappointed response. Now i doubt where something is called customer satisfaction with amazon.
So at last because i am being as an amazon customer i have wasted my valuable times and my loan money have stuck in amazon wallet. Now amazon started to command me to use their catalogue and i strongly resist doing so. I cannot buy the product which i don’t want. Because you are selling something doesn’t mean that i have to buy it. I cannot give up on my money and i don’t let amazon to command my interest. Now i need a final answer about what is next. Then only i can decide my move to claim my money back.
Note: to amazon’s knowledge, the lender have accepted to cancel the loan if amazon has cancelled the voucher and returned the money back to zest money. Also they have sent and mail to confirm this.
Looking forward for someone to get in touch immediately.
Very disappointedly,
Naveen
