Lounge Suite broke twice within 9 months

I bought a corner lounge from House and Home in July 2015. Within the first 4 Months the back rest were coming loose and the cushions were slouching. They came to repair it at my house. About 5 weeks ago the recliner broke, aswell as the back rests are in the same condition again as the previous complaint and the lounge is slouching again. I reported it and with a strugle of 4 weeks they sent an repair agent to my house. I have requested a replacement or a refund of the lounge as it is the second time. Now they say they cannot. It needs to break 4 to 5 times in order ro be replaced. They want us to take it to the store where it will be sent for repairs for 1 week or longer. I do not have extra lounge. Where do they want us to sit. This is not exceptable as it is still under guarantee.<br>
