Poor quality and expensive couches

I bought lounge suit at bradlows in 2016 december costing 18000,last year i wrote to them about the tearing of couches i even suggested to change them cause the tearing was very bad and seem to continue on all couches but they refused and fixed them. But righg now all the couches are in bad state if i had money i was going to take them to the bin but i spent lot of money on this couch and i need explanation.
