Amazon — Wrong mode of refund

Address:	Bangalore, Karnataka, 302015
Website:	Amazon

I purchased a towel product from amazon on the basis of reviews done on that product. I realized that the 5 star reviews done are fake as those who had done reviews got the product for free so i inferred that product is not worth having and i cancelled the product before i received it. But still they delivered the product to me even after cancelling the product. Since, i wasn't at home so my parents accepted the product and paid cash on delivery. When i came to know regarding this i called customer care & told them to refund the money to me & take their product & refund should be done in the form of cheque, not gift voucher. I also wrote a mail in this regard and they assured me that refund will be done in the form of cheque. So i returned the product but when i received the refund, it was still in the form of gift voucher which basically means that my money is locked with amazon & i will have to use that 399 for shopping on amazon only. I called the customer care in this regard and they were not at all helpful. They said they can't do anything in this regard now. I confronted them that why didn't they adhered to my request for which they had no answer. They didn’t comply to their own words. Earlier, they had convinced me that the money will be sent in form of cheque but now they are not doing so. I want my money back & i don't want their gift voucher. Kindly help
