Flipkart — Cancellation of return

I had purchased a product of roadster denim which I would like to return now. I made 3 attempts to return it but within 2-3 days they cancel it. They don't allow me to talk to consumer care. The order was placed on 4th of December and received it on 8th of December. The return is valid till 17th of December. They are cancelling without mentioning sufficient reason. My reason for return falls within there return policy but still they have cancelled it. If you can help me with it I would be thankful
