Brand new lounge suite

We purchased an expensive lounge suite from a dealer, once it was delivered we complained about the two couches, the dealer placed a complaint with them on our behalf in March. It took them at least two weeks before someone from Grafton came to view it & put in their report. Then eventually the report came back to uplift the couches & replace them. Another three weeks later, we had to continually chase the dealer to chase Grafton as to when they were collecting . After another two weeks & us chasing regularly, the shop finally came back a week ago & told us they would have to uplift the couches, as Grafton don't collect from residents homes, only shops. That was done by the dealer last Monday & since then we have heard nothing, and without any couches to sit on. How can a reputable company like Grafton Everest treat their clients like this. Really not impressed with the way we have been messed around & recommend that others take note of the kind of service received from this company!!
