Sir i ordered a shoe from myntra! And returned that due to size issue! On 10th of january they told me that they have initiated a refund for my 1596 rupee, and told me to wait 10 days! Today is 26th january and still i haven't received any refund, they provided me with a reference number which the bank is denying to accept to give u information! I also contacted the branch of my bank where they clearly told me to contact the myntra as they cannot help me with a reference number only they require a particular utr number! Which the myntra is denying to provide me with! Even they are not ready to help me out further as they say that from their side they escalated the money whether you have received or not thats not our concern please help me out! (I have attached all the documents), chat with my bank, the googe pay customer support (As i paid via upi google pay)
