Samsung Zflip screen repair

So I bought the Zflip4 last year February and since I’ve had it the part were the screen folds has been the biggest issue. It first shows a black line then the screen completely blacks out then it eventually lifts. The first time this happened it was horrible but Vodacom was able to fix it as the phone was still under warranty. The same thing happened again now it’s not as bad as before but the screen is completely blacked out and has lifted where it folds. Took the phone in to Vodacom stores and I was told that per the Samsung policy this problem cannot be fixed as there is physical damage to the phone. Of course there’s damage, the freaking screen keeps breaking itself. I then called the Samsung repair center in Jhb to enquire about this and I was told that this is not covered under the given warranty, HOW?! when the damage wasn’t caused by anything I did?! My warranty apparently expires on the 20th so at this point it just seems like they are trying to shift blame just so they can evade responsibility as promised. I will physically go in to the repair center later today so all this can be explained cause right now it doesn’t make any sense to me. Don’t buy these Samsung flip phones if your phone is part of your main work equipment/form of communication cause it’s nice, cute and compact but this folding thing wasn’t done right, it JUST BREAKS ITSELF then Samsung refuses to take responsibility for the impracticality of their flip concept. I’ve searched for social media reviews on this phone (which I should’ve done before I bought it) and this looks like a common problem amongst these phones. Like I said, the first time this happened, the phone was worse and they fixed it without any issues but now I’m being given all sorts of bogus excuses as to why this can’t be covered under the warranty
