Bad quality of goods

So furious...not only were we sold bad quality goods we were always treated like stupids and made out to be *****. My husband and I bought a dinning room set from the Cresta branch in October 2013 and paid cash. Last year December we noticed that the table seperated at the joints and we asked to have it changed. In January this year we got a new table but it wasn't the same size as the original table we bought. We sent it back and once again they brought the wrong table. When we spoke to them, we asked for photos of the original table and wanted the sizes. We were basically told that we are lying as the original table and the size we initially got was the same as the new table that was delivered, but I know for a fact that it wasn't. I then requested for my old table back and was told that they repaired it and sold it to someone else, and I was tired of complaining and just left it at that. I am now sitting with chairs that are pulling loose and material getting loose, if I knew I was going to have so many issues, I wouldn't hve bought it and I can afford to buy new furniture every second year. I want my money back so that I can go to another shop to buy decent furniture
