Myntra - Part of my order was not delivered

I ordered ** items from Myntra on *th June. Among them, they only delivered one time on the *th of June and schedule the rest items on the *th and *th of June, but they delivered all items on the *th of June. The item which they delivered was supposed to be a Louis Phillipe men's belt, but they delivered us the wrong product a face toner which was some other girl’s item. I informed them on the *th of June and they raised a complaint. The next day on *th June they only arranged a pickup of one item which was delivered wrong and I got the refund back. But still * items are missing , every other day from then I am contacting them , few have raised a complaint and some closes it from their side. I have spoken to dozen of customers executives named Jyoti, Ravi, Pooja , Danish, Garima, Monu, Alia Sameer and many more. From day one they are asking to me wait for ** to ** hours maximum but nobody gave me any resolution.
