Homemark Scandal

I bought an Air-o-Space sofa bed at Centurion Mall in November 2021 and within a week it would deflate. I returned it and I was given another one which had the same issue 2 weeks later (it deflates on the same spot). I took it back as well and I requested for a refund, in which they refused. I was told it can only be repaired, no exchange nor refund. In Jan 2022, I collected it after it got repaired and when I got home, only to find out that it was slightly torn between the section that connects the sofa and bed part. But I just wanted to see if the initial matter was resolved. Yes it was repaired but now it deflates on the opposite side. Today I went to the store to report the matter and they're saying I must take it back so that they can fix the new hole. I'm so irritated because its clear that there's a manufacturing fault and now I must bear the shortcomings of their production inefficiencies. I just want my money back now because I'm not getting value for money or at least get a different product for the same value which will give me inner peace. Furthermore, its a waste of my time now having to keep visiting the store to inform them of my dissatisfaction. It is utter nonsense that the customer must be punished for their mess. It is their duty to ensure proper quality assurance on their product before it is sold, if that fails, they MUST acknowledge their production shortcomings and not pass it on to the customer.
