complain due to poor quality of the coaches

I bought a coach(L shape) last year November (30 November 2019) it was 5k if not 5.5 k , i called the store this year March (2020) before lock down , complaining about the quality of the coach and how i'm happy , i have been told that North-riding management will give me a call , i waited for a week no call , then i have to get someone to come and assist me with the sponge to lift the coach up , around May 2020 i DM decofurn on Instagram they requested my invoice which i did send and coach pictures , i only received a text on the 19th May 2020 stating that they will contact me once they open , Last week of May 2020 (around 25th ) they open , i gave them a chance to settle , till to date i have received any call for investigation or just to tell me that they will call me ....... your service is poor , your products are just for decor not use after spending R13K which i sent proof no one bother to call and check on me ...... i regret setting my foot on your store .....i want my money ...i worked hard for it ..... *** ***
