Myntra.com — Wrong reporting of return requested product

Order ID # 1189806 [protected]
I received a product whose size was small and bigger size wasn't available, so I requested its return. The person came to my house, but without even seeing the product he wrongly reported that the product had missing tags, which aren't. I raised the issue with Myntra, they asked me to upload the picture of product, but I'm unable to upload the picture on their app due to some technical issue on their app or whatsoever. Now I am stuck with the wrong product with no assistance or anything.
