Bad quality couches

i bought couches last year and now they are making a funny noise. called sedgars to come fetch them, they did to sort of fix the issue. upon returning them the sound is still there and i just hate them. i have spent a fortune on this couches for them to sound like they were bought 50 years ago. the quality is bad for R60 000 couches. They must come and fetch them i don't want them anymore
