Address:	560080
Website:	www.myntra.com

I have placed an order on myntra on 27/11/18 for a pair of shoes vide order number. 1095158761139908085903
I was supposed to have received it on 30/11/18
To date the delivery hasn’t come
Despite repeated calls and promises from myntra the matter hasn’t resolved yet
On the 7/12/18 i placed a request to cancel the order but myntra won’t cancel the order and they won’t initiate the process of refund of the amount
The officials are rude too
They won’t answer my repeated requests and now they do not come on the phone to talk to me

Can anything be done
Will i lose my money and not be able to do anything about it
Pls help
