Amazon India — Refund reference number and refund not reflected

I returned one product. Order Id is[protected] and it's price is 987. In Amazon refund status shows that it's credited on 23 jun but it's not reflected on my payment method so i contacted my credit card company they asked me for Refund refrence number and it's not generated yet and I raised a ticket about RRN but they keep postponing date. First they told me wait for 5 days. then when i checked after 5 days they said same thing. I've never faced this kind of problem with any E commerce site. Plz solve This problem ASAP otherwise i will delete my Amazon account
