Inferior Quality sold to me

I spent close to 50 000 rand at House of Saleem Glen store over the past year- This means that I have been a loyal customer... and need to be treated with care. I bought a glass coffee table in 2020.... 5 months later the glass fell off but did not break, I then took it back as I was said that they cannot exchange it but they will fix it- with convincing they claimed that the coffee table was exchanged. I picked this up from the store, took it home only to find out that this coffee table was inferior as the swivel glass was touching each other when turned. I then immediately called Saleem who said that this is strange and that I am the only customer complaining and that they sold a lot of these. I then left it as is until 2 moths later the glass fell off again. I called Saleem on the 1 December to inform him that the glass has fallen again and explained that this is a risk because my mom could have gotten hurt and she is 76 years old- The response I received from Saleem was that they cannot give me a different coffee table they will fix it again but I must wait until next year. What type of service is this for a reputable Company. I am under no circumstances taking this coffee table back- I want an upgrade even if is any cheaper coffee table. To mention that I had tried calling the store at-least 5 times from the morning and no one was prepared to help me.
