Myntra.com — unprofessional delivery executive

Address: Yadav Niwas, Opposite Jiya Boys Hostel, Subharti Road, Kolhupani Lower, Nanda Ki Chowki, Dehradun, Uttarakhand, 248007

I placed an order on myntra with the order id:[protected]-5198303 on 02/10/2019, it reached me on 06/10/2019. The delivery executive called me and i explained him the address which was already clearly mentioned with my order. He agreed to come but after sometime i received a message and an email for a successful delivery of my order. Then i reached out to him and then he rudely asked me to come to him as there were other orders for him to deliver too. And when i went to him he was very rude and didn't even answer anything i asked.
I tried reaching myntra support through the app but the help centre showed only one option for a reverse call and that too was inaccessible.
This huge company and it's partners are so irresponsible and unprofessional. I want them to learn a lesson and be more supportive to the customers.
