I had purchased a product on 10/09/2019, priced ₹959 through Amazon, which was supposed to be delivered latest by 28/10/2019. On not receiving the product within the stipulated time, Amazon chose to refund me back my money. Another product was purchased on 18/09/2019, priced ₹499 through Amazon, which was cancelled by me and again Amazon initiated the money to my account. In both the cases the money is still pending to be credited into my account. Amazon had initiated money to my bank account, account number- [protected], twice with reference numbers[protected] and[protected] for the amounts of ₹959 and ₹499 respectively, which is yet to be credited into my account. The stipulated time period that they had given for the amounts to be credited is already over. Please do the necessary and oblige.
