I order from swiggy on 26 sep 2019 amount of 99 rs order. But his restaurant partner gave me wrong food. I complaint and want to refund. They told me refund is in processing and show in your account with in 24 - 48 hours but i wait for above 48 hours but till 30 sept 2019 refund not show in my account. I chat with swiggy customer service and ask the status they told me refund already credit on 26 sep 2019 with refund id 21529903. I show they my account statement there is no credit any amount from swiggy but they did not agree. I ask for tell me the account no which you credit this money they told me please contact your bank. I ask them again for transaction no. For enquiry from the bank because bank want transaction no. For enquiry. They told me they have only refund id and request id. How is it possible if they transfer any amount bank generate transaction no.. So again i ask them for please tell me which account you transfer this amount because i want to know for his transcation right or wrong. But the customer executive gave me defualt messages like i apologies for your disappointment etc. They not support for my refund.
