Ghosted and Bad service

last year I bought a Samsung tab A8 for my sons birthday , spender extra on a screen protector and a rugged cover , i have been having constant problems with the tablet with random reboots while trying to view anything on YouTube or while an app updates

I have booked the tablet back fort a replacement as it was still under warranty , trying to get the issue resolved and the process to be completed sooner I asked for a refund or exchange , so they credited me so I wanted to get a new same model tablet that is now R500 more and I lost the screen protector and sitting now with a rugged cover worth R450

I have escalated to takealots ceo as well and now iam being ghosted , Thank you alot takealot , Please people dont buy electronics from takealot as when it breaks just imagine the face of your child and the disappointment and the leadership from a huge retailer like takealot well iwas expecting results , what a shame will be **** my business elseware , this is by far the worst experience i had buying high value electronics and after service , ghosting a client in 2023 , well i have send emails again and again still no answer ... i really want to tell the CEO in his face what i think of him and his company after i have the experience of disappointment from my child
