Myntra.com — Refusing to exchange/return a wrong product.

I have orderd an "ONLY woman off white and mustered yellow checked casual shirt(XS size)" on 22/06/2020. On 2/07/2020 I received the order. When I cut open the packet I realised that I have received a wrong product consist of a VEROMODA girls talk ss t shirt in, snow white (L size).
I have contacted to" MYNTRA CUSTOMER CARE" on 2.07.2020 and they said that they will deliver the product on 6.07.2020. But the order did not arrived on that day.
Later, Again I tried to contact to MYNTRA SUPPORT and they said to wait until 15th july.
ON 11.07.2020 when the delivery person came, he denied to took the product and exchange it with the right item because he told that he does not have any information regarding the WRONG PRODUCT that I received. After this again I contacted with MYNTRA CUSTOMER CARE and they said to wait for 24-48Hrs.
Today is 15th July and the ordered still didn't arrived to me. Today when I called MYNTRA CUSTOMER CARE then they said that the complaint which I have launched has been DECLINED and also told me to wait for 24-48Hrs.On 26th July when the delivery boy came then same thing happened again, Again I contacted with customer care. They said they will inform the delivery boy about the matter. Today on 30th july again when the delivery boy came again the same incident happened like 11th july.
SAME THING IS HAPPENING AGAIN AND AGAIN BUT I AM NOT RECEIVING THE ORIGINAL PRODUCT.
It is my concern that almost 14days already over and till I didn't get the right product. Please look into the matter ASAP and exchange the wrong item with the right item as soon as possible.
