They have provided sofaset mentioned specifications as 7 *9.5 feet where as when got delivery we have noticed that size delivered was not correct

We have purchased sofa from sumeet enterprises. While purchased they mentioned sofa size as 7 * 9.5 feet sofa when it was delivered found sofa is width 7.9 and length is 9.5 feet which is not fitting to my hall size. When I called them they are not ready to replace or resize or return so this is unacceptable... This sofa is not feeting to room and they are saying we will not exchange , replace or repair. We requested them to either of below option but they denied all below 1. replace and deliver correct specifications sofa as mentioned while selling 2. Exchange sofa with another sofa of my hall size 3. Return sofa and refund full amount with transportation and delivery charges
