First Cry - Half product delivered

I have paid membership of first cry(club membership) and ordering from last one year. This is first time I am disappointed with the delivery, received half product. I ordered frock with bloomers. Received only bloomer, NOT frock. When I raise a return request with proof, then rejected my request and when I called them to know the rejection reason . They said at their end all things are packaging. That means their customer are lying, it's not about the ***/- , I can leave it but such kind of brand doesn't know how to maintain the old customer ship. I want to raise a complaint how careless they are while warehouse packging. If they want proof for us while refund share the pics which I uploaded. Then I also want proof what they have while packaging. How I can trust if trust able issue raised by those side. I want full explanation with proof.
