Myntra.com — behavior of delivering agent

I have requested for exchange of puma men blue croatia idp sandal. I was in my office & my mother was there. He denied the exchange first, then told my mother to clear off the slight dirt which is on sole of the sandals. Then he asked my mother to wash it off. As soon as i came to know about this, i called him asking about his unprofessional & highly unacceptable behavior. He talked rudely & i am sorry to say myntra is using pathetic courier service. I will surely raise this issue. These people disrespect their customers & i want some stringent action so that it didn't happen to others. I would not like to continue my love for shopping on myntra after seeing how unproffesionally they deal with the customer request.
