Tablet

I received bad service in China mall bought child tablets in December 2025 and it lasted only 3 days then started to freeze, I went to the shop they still exchanged and gv me the same brand it worked almost a week it did the same thing and they advised that warranty is 6 months but now they refuse to fix or change it, how do you sit with something that is not working while it's within the warranty, and your not a happy client, my child can't navigate it at all because it keeps freezing
