HP Victus 16 Laptop Screen Flickering - Shuts Down! Full Refund Demand

My HP Victus 16 laptop's screen keeps flickering on and off, and eventually it shuts down completely. I'm completely dissatisfied with it and haven't liked its performance since I bought it. I don't want to run into the same problems and have to pay ridiculous amounts of money right after the warranty expires. I will take it to MediaMarkt for warranty service tomorrow, and I do not want to pay any fee. I don't want this laptop at all; I've become so fed up with it that I demand a full refund. Otherwise, I will file a complaint with the Consumer Arbitration Committee and include these videos as evidence.
