Flipkart — Harassment by support staff return/refund

I ordered a shoe size 13 and got it delivered yesterday, size fit is my issue so I raised a return request, delivery person rudely failed to return pick up saying the shoe I received is not shown orange colour, why Flipkart being on the lines of harassing customers and annoying customer like me, return & refund now, as per your own return policy I am returning the product not liked to my expectation due to amalgamation of reasons.
