Faulty Fridge

I bought a Hisense Fridge on the 2nd of May 2024. On the 22nd of August I realised the in walls of the fridge are cracking (white wall). And log a query and was advised there is nothing they can do about it , it’s not covered under warranty I must contact Hisense to fix it at my expense . The fridge isn’t even 3 months old and I did not buy it at Hisense I bought it at Game . Am really disappointed
