Hi,
I payed the amount for order on 28th of April, 2019 and Amazon received the amount on 29th April, 2019 . This information i got from my credit card company .Here is the scenario
The delivery guy came to my address and he ask for payment as it is COD . But I canceled the order in front of him due to his machine not accepting my credit card . My app was showing the product is canceled. But delivery guy system was showing it is not canceled .So he ask me to pay the amount through pay link . I have payed the amount using pay link which was generated before cancel . Now my card successfully payed the amount to Amazon and the delivery handed over the product . Then after 30 min delivery boy came back to my address and ask for the product because his system was showing the product is canceled and he took the product by saying i will get my refund after 7 working day . Today is 24th June, 2019 till now i didn't receive my money .
I have called customer support but they are always saying that i will receive my money with 4 to 5 working day . I have all call records and mail chains where they are rejecting that they didn't receive any amount for the particular order . But i have a proof of my credit card statement which is clearly stating that i have payed to Amazon Bangalore .
