SAMSUNG Z FLIP 4 - SCREEN ISSUES

I am utterly disgusted and appalled by SAMSUNG and their Z FLIP 4. I purchased my phone in April 2023 (on contract). Lovely, beautiful looking phone, unfortunately that's where it ends. 2 months into using the phone I started experiencing issues with the screen and the flip feature. A few months down that line the phone screen just went blank. Mind you this happened overnight. I went over to samsumg in Umhlanga and handed in the phone as it is still under warranty (phone isn't even a year old at this point) weeks and a month passed and I didn't hear back. My hubby decided to pop by this morning and was advised that the warranty was rejected. All he got from the consultant was "sorry its rejected" and was handed the phone. He then spoke to a manager and she said "rejected as they phone that the phone was dropped" how ? We definitely did not drop that phone. Other than it going in and out of my pocket or handbag it was never dropped. She then goes on to say "when you purchase expensive phones like this you must take insurance" so please explain to me what the warranty is for? Furthermore, I think every person that I have met has had an issue with a flip phone from Samsung be it generation 3 or 4 and its all the same issues. Samsung, Please explain, how can you design a phone like this? How can you put your customers through this? People warned me to not purchase this phone and now I know why. Now I am busy paying for this contract which isn't even a year old and I don't even have a working phone.
