My Dune Sofa now qualifies as my worst purchase ever and the subsequent customer service has been even worse. The sofas look great in store but god help you if you dare to sit on them... they just turn into a total mess, mine looks at least ten years old after a month of use.
Normally if you were dealing with someone decent this would be easy to resolve but not these cowboys... email and complain and they will reply by saying what a shame it is that you are not happy with your sofa but that's about all you will get from them.
I will see you in court.
