Urgent Complaint: Unresolved Refund, System Error, and Unprofessional Supervisor

I am writing to formally complain about an ongoing issue with my recent order and the unacceptable customer service I have received. My product was delivered on 30 September, but the order status was never updated on Myntra end, which prevented me from initiating a return. I have been contacting Myntra’s customer support team since 30 September, but no resolution has been provided. Today, I spoke with a female supervisor who was extremely rude and unprofessional. She claimed that the order had been cancelled and that nothing could be done. When I requested to speak with a senior representative, she disconnected the call instead of addressing my concern. This is completely unacceptable and reflects very poor customer service. I have tried reconnecting multiple times, but the call did not connect. Furthermore, my account was logged out from Myntra end, and I am currently unable to log back in, which is preventing me from checking my order ID. Please check and resolve this issue as soon as possible, take action against the responsible party, and process my refund. I have both the product and the invoice with me.
