Bad after sale bussiness

Recently I,purchase a six seater lounge suite from House & Home Tokai Cape Town that was manufactured by Goma Goma.two years later we discovered that back rest foam support was disintegrating of the lounge suite.I wrote to House and Home on the 23/11/2022 and forward photos to substantiate my claim,however,three weeks later when I had heard nothing from the store I went to the the store to ascertain what was the hold up.I discovered that my complaint was not forward o Goma Goma for accessment and only sent to Goma Goma on the day that I brought it to their attention. I spoke to he store manager ho said the suite was out of warranty and that I must pay one of their service providers to repair the lounge suite..I had a lot of faith in this company because over he yeas of my married life I purchase a lot of furniture from them ,recently I purchase R16000.00 worth of furniture from them. I now discovered that they sell inferior products to their customers. Why must I pay them to repair my lounge suite that cost me R11000.00 at the time when I purchase it.The store Management was not very keen on helping me which lead me to believe that after sale business was not important because they achieved heir targets for the month. He made feel that because I was a pensioner he made feel that I was bing a nuisance and wants to get rid of me.
