Meesho — I'm complaining about a delivery issue

I personally loved the experience of Meesho app, but lately I placed an order but it had been cancelled by the delivery person for no valuable reason, i request him for online payment and to leave the package infront of rahe door, but he started misbehave by words ...
I felt too bad for the way of his speech!!! If possible kindly allow your delivery employees to know about the customer service
