Malfunction - of a phone

I bought a phone, Honor x8, on the 17th of May, the very last month, hardly even a month, the phone is starting to show me flames, within 2 weeks it had started to freeze and restart on its own - I thought to myself, let me give it a benefit of a doubt, only to be met by yet something that dragged beyond, since yesterday, 15th June, I was without a working phone - it did what has become a norm to me, FROZE - then restarted, over and over again up until now - now that's the worst experience I've ever been exposed to in the history of mobile phones - I can't wish, even the worst of my enemies to go through what I'm going through - i think they should discontinue the manufacturing of this apology for a phone - now I don't know what to do cause on the slip I got when I bought this nonsense phone there's a note at the bottom that says "final date for out of box failure returns is 23-05-2022" , only a few days after if purchased it - I'm under siege I rely on my phone to run a lot of things and I can't afford to buy a new phone right now 😳😳😳
