Item supplied not as stated in shop

(page 2/2) now I have moved into a house paid for a lounge suit that is not as promised by the sales person in the shop, management are trying to bully me into taking this cash offer deal which I feel is not fair. After discussions with management they are willing to offer me only R1000 cash back to keep the set as is. Although a 5 seat recliner will sell for R4000+ more. Curtains to fit with the set have already been made to order and on route. Table to fit with this set and the colour has to be collect from another supplier and now nothing is as it seems. Management has just phoned to say that either I take the cash offer or they will come and fetch the set and refund me in total, because the sales person on the floor didn't know his product and now I refuse to be strong armed into a deal which I feel is not fair. I have a very expensive lounge set which is not what I was promised before purchasing curtains specially made to fit and tables on it way and no happiness.
