Myntra.com — myntra pickup

I had scheduled for a pickup and its been failed for the 3rd time now. The executive dosent call me or they don't show up. At the end of the day i get a message saying pickup has failed. The number of the delivery executive will either be switched off or they won't attend the call. This is highly disappointing. I want the pickup to be done latest by saturday (19/10/19) or this will be the last time i'll be purchasing from myntra. There are better apps with better customer care facilities. You guys suck at customer care and after sales services.
