NCF Living complaint: Dirtystained sofas

I brought brand new sofas and was expecting brand new sofas delivered to me! Instead I get delivered dirty and stained sofas and got told that they will replace it if I call to tell them it came dirty and took pictures. I did all that and till this date I have heard nothing. They were delivered on the 8622. It has now been more than 3 weeks and they still haven’t bothered to resolve this. I have sent numerous emails and made calls after calls, can’t get connected to anyone and made visits to the showroom only to returned back with false promises. I am absolutely fuming over this disgusting customer service and I want this to sent to head office. I want a full refund as I do not want anything to do with NCF. They need to come and take their dirty sofas back! This is not acceptable. I did not pay for dirty sofas and I’m not willing to keep them in my house any longer. Please assist me on this.
