I had placed an order with order no:[protected], [protected] on Myntra which was delievered to me on 18th August and I had placed a return request with 2 times on the same day .I was provided a waybill no :[protected]and was told to wait till 23august for the pickup. But no delievery agent contacted me for the pickup, I even contacted xpressbees the assigned courier service regarding my pickup but they said the fault is of myntra.I logged a complaint regarding it through Myntra customer support and I was told to wait for 72hours from 23 to 27 that is today those 72 hours are over and whenever I am calling them they are just telling me to wait for next 24hours. Plz arrange my pickup and return my money, how can u just trouble your customers like that.
