Myntra.com — Incorrect item received

I ordered the following item and apparently got the package for delivery on 20 Jun - ADBUCKS Women's Light Blue Solid Denim Lycra Jeggings But to my surprise got a mens chappal - the box had my name and address on it but the invoice inside was for someone else.

I tried to raise a return request selecting wrong item received on your website but it did not allow to send a photo of incorrect item.
The delivery guy came the next day to my surprise with my correct item but refused to hand it over to me and that the chappals back as he claimed he wanted a jegging in return of a jegging. When explained he said I need to call CC and raise a separate complaint
So I called and they said made a note of it - next day delivery agent came and was the same situation and they closed my open query / complaint without checking with me
I wrote to you all very frustrated on a chat and they said they made a note of it - After 3 days delivery agent came and same thing - refused to pick the chappals up and the query was closed again without any intimation to me
I called in absolute rage and spoke to one of the floor supervisors they gave me the same jazz and said will take action against the delivery agent and raised a complaint - For the first time I got a complaint # IN[protected] with ETA for 3-4 days
After 3 days delivery agent came and refused to hand over my correct item and take the incorrect one back.
I called again to ensure no agent knocks my door if they are not willing to collect still the delivery agent came
Delivery agents have no clue of the situation, do not know how to talk to customers
TO my surprise later the exchange for jegging was cancelled and query closed again
I am left without my item and no refund to it + sent an email to grievance dept with no response
