Myntra.com — I didnt receive my product,its showing delivered

I did not receive my product .I received a call from delivery agent and I told him that “I am not at my place either you come tomorrow or deliver to security agent.He himself told he will deliver to security.In evening I am getting to know no parcel delivered to any security on my name.I called delivery agent asking about my parcel .he was least bothered to answer where he exactly delivered the parcel.Thereafter he didn’t pick my calls up.something was so off about him.I want either my parcel to be delivered or refund my money..Though I am a regular customer of myntra..this kind of courier service is ruining my trust on myntra.My colleagues from had faced similar problems it seems ..but myntra had called them and told it was delivered nothing can be done..then what’s the point??The delivery boy should have called me back and told what happened with the parcel..it’s like nothing ..Such a huge bad experience .Kindly do the needful 🙏
