Failure to service or exchange the factory faulty fridge

On the 30th April I have bought a Hisense 481L side by side with water and Ice despenser. The fridge only worked for 6 days then the fridge was warm inside. I have then requested for an exchange but was rather told that it impossible. They then sent a technician to fix it (brand new fridge) of which could only work for few months and started malfunctioning. It was warm again, I then logged for a second service request on the 21 September 2022 but no feedback until I logged the second one on Saturday of which is when I got the ticket number. I have then followed up on Tuesday 26 Sept 2022 on this service status and the technician only came on the 29 September 2022.

The feedback was, the fridge is leaking gas and it faulty.

I did phone Hisense service department that's where I was told to wait as they are awaiting on the report from the technician. Even today the fridge is not be fixed and no one is telling me something tangible.

I am hurt because I bought a brand new fridge and it get fixed twice in 5 months.. It now like I have bought a bad second hand. They are not mentioning means to refund my groceries and they don't have a quick turn around mitigation ways. I am so disappointed
