Address: Vasundhara Girls hostel,Indore, Indore, Madhya Pradesh, 452010

I have order cloths from mynthra online shopping by cash on delivery. I am working in a multinational company because i have 10 minutes to came out from that place. During mynthra delivery time, delivery boy call me for the product an he is very rude behavior for the delay. I have many time told him i will come with in 30 minutes, but he is not ready for waiting. But this is not my problem he scold me for the delay through phone. He scold me for buying products by my own money. He is only responsible for the delivery. If i compliant this with myntra till now i didn't get any clarification from myntra.
In myntra messege they told the product will deliver by this number owned delivery boy ([protected]) but i recieved the call from this number([protected]).
