Myntra.com — delivery agent picked up the return item but myntra has not received, return status is showing as cancelled

My name is rohit i had ordered two shoes, one is nike low borough and another one is hrx white sneakers and got the delivery of the products. Later, i had raised a return request for both the product by mistake, i only wanted to return hrx shoe and exchange nike shoe and i was not getting any option to cancel the return request for the nike shoe so i called myntra help line number and asked them to cancel the return request for nike shoe only, but they said they are unable to cancel the return request and they asked me coordinate with the delivery partner. Today (29.07.19) the delivery boy came around 1.25pm he didn't call me before coming to my place because he knows my place as he was the guy who delivered the product. So i told him i want to return the hrx shoe not the nike shoe, he collected the hrx shoe and did something on his device. After few minutes a got a call from myntra stating that if you want to cancel your return request for hrx then press 2. I told the delivery boy, i want to keep nike then why it is telling hrx, he told me to confirm the cancel, and not to worries as he collected the hrx shoe and they have a tag which they need to scan but he is not carrying the tag, once he reach the office he will scan the tag then the hrx shoe corrct return status will be shown on my mantra app i agreed because at the time of delivery, he delivered the product still in my app it was showing as out for delivery and at night the status got charged to delivered. At 11.30pm i checked my mobile and found messages and emails from myntra, i got shocked as i read those mails and messages, there it was mentioned that the return request got cancelled for both the product, immediately i opened the myntra app and checked the order section, there also it is showing return cancelled again return and exchange options are showing. I got frustrated and i called myntra, they told me they have no clue. I was cheated, i lost my money as well as the product.
