Customer Service Horror

This is an incredible product. I always double check reviews before purchasing any product and the review about this item being of great quality and very modern, seemed to be a perfect fit. We are renting, so we have limited ways of modernizing our home, however, this wallpaper, would be a perfect fit. I ordered 2 x off the BF 3D Self-Adhesive PE Foam Ceiling & Wallpaper Panel MW-206 (multi-coloured). Please read that sentence again. When the package arrived, I received 1 x multi-coloured wallpaper and 1 x light brown stone-like wallpaper. I've logged my return and requested that my item is replaced. Today marks 3 days since the incorrect item was returned. I have received no update, no feedback, no email, no sms, no phone call as to the status of my return. Don't get me wrong - I understand that companies have policies regarding matters and procedures like this one, however, I feel like this error, was not mine, but I am the one suffering now. I think you really have to re-look customer service consultants and teach them how to handle situations like this one, better than this. I'm sure whenever my item is returned, it will be as great as the previous review mentioned. But for now, I cannot say.
