Myntra.com — received different product and refund not initiated

Dear sir,

I have placed a order of h&m women white jersey crepe top in size small on 22nd july 2020 (Order number[protected]-2038403) it was of rs 799/-.
On 27th july 2020 the order get delivered to me but it was not what i got delivered, instead of h& m top i received h & m trouser.
I have put the return request stating the reason for returning the product, on 28th of july 2020 one person from myntra came to pick the packet but when i told him that the reason for return is that i have received the wrong package he said for that authority permission is required and he put my request on hold.
Now since then i have not received any mail or massage from myntra regarding my return request.
I have wrote the same problem to there help centre also there its shows the status of my complaint is resolved but whats the status of my problem when will they pick up this packet or when i will get my money back???

Return number: [protected]
Kindly look into the matter and solved the issue
