Very disappointed

I have bought a gomma gomma lounge suite and the seats are sagging and arm rest are pealing. But when i purchased it i was informed by the sales person that this is a very strong type material and would not peel like the others. So I went to the store to complain and i was informed there is no wear and tear guarantee, the garuantee was uo by 24 months already and i have been paying theses chairs off for 3 years. I must make my final payment then its done. I paid over R20000 for this chairs. I feel ****** and **********. Because the only reason why I paid so much for a lounge suite was because it will keep for at least 5 years and more guaranteed. They said even the manufacturer doesn't have a guarantee. How do they expect people to buy again if this is what they do with you when you almost done paying the item. I've sworn that i will never purchase anything again in my life at homechoice!! I will also not recommend any customers to them. I feel deceived and hurt!!!
