Myntra.com — Exchange product not accepted by Delivery agent stating below reason

I received wrong product from Myntra & while exchanging product delivery agent provided below reasons and kept the exchange product on hold.

This product cannot be exchange due to high price value of exchange product. May I know answer from Myntra if they have provided the wrong product at high range where there is customer mistake?

Also please be informed, I ordered earlier Roaster jogger of waist size 36 (refer Myntra bill screenshot) and I received product from myntra which is totally different - it wasn't jogger normal roaster jeans with waist size 28
