Myntra.com — Item missing

Same issue happened for me too.. i purchase boult audio for the offer price of 899 on 23/12/2021.. i recieved courier on 31/12/2021. i just opened the box and i seen an crushed box of noise air buds and a an invoice copy of other customer. i shown it with delevery boy and he said they have nothing to do raise a complaint with myntra. At the moment i raised complaint and today 04/01/2022 i recieved their message that .. From their side no issue and the product was packed after quality check. and footage shows its packed. i dont know what they are doing while quality checking. i recieved an empty pack of other product and some other customers invoice. they rejecting my complaint. This product has no COD and return policy available.. I am cheated by myntra online shopping app.. Never trust these app. they are asking for unboxing video for refunding.. Is all customer are taking unboxing video for uploading on youtube.. i asked for package video and they were never send that to me.
