Myntra.com — Received wrong product and delivery boy refused to pick the product when I placed return request

I ordered the U.S. Polo Assn. lounge pants (Pure Cotton White color size M) worth Rs. 1149/- on 16th March 2023 at 19:33 pm and received my parcel on 23rd march but when I opened the parcel, I got a different product. Then I placed a return request on the same day clearly mentioning the reason and the next day the delivery pickup boy came and refused to pick it up as it was a different product. Then I tried to call customer care but failed to talk to the customer care executive and then I placed a return request again. I got an option chat with us in the Return Help option. I talked to a customer executive on the chat messenger and she convinced me to resolve the issue upto 27th of March. On the next day (24th March) in my app return request was removed and instead of that it was displayed that the issue has been resolved by showing "the product is delivered" and also the chat with us option was disabled yesterday. But no delivery agent came to receive it. Yesterday once again I placed a return request but today i.e.[protected] the delivery agent again refused to pick the item up. I have never faced such bad experience on any shopping site.
