These are the order I’d’s of the orders I want to return. I had ordered multiple orders(total * orders) during FK big billion days sale out of which I had to return * orders due to various reasons like size or fit problems. I had raised return requests multiple times also shared photos of the product(there is no other problem with any product rather than size) but there was no response from FK. They kept me on stand by for more than ** days and then they cancelled product pickup and now they are denying for pickup or any return requests stating that return policy has ended. When I tried to reason with fk cc executive they said there is nothing I can do to return these products. Now I feel cheated . Most irritating part is that whenever you call them they make promises of pickup and ask for time of * or * days and then they cancel the request without informing.Help me out here Voxya community
