4 Weeks later and its Physical Damage what nonsense

I purchased a Samsung Z flip 4 from an mtn store via contract . Initially i was told that this is the dual sim phone which was a lie after unboxing and the Mtn consultant advised that the samsung rep misinformed him . The phone had all protective gear . The phone kept on switching on and off and going on E which prevented me from receiving important emails and messages , the battery life was 4 hours and less and then this one day the phone doesnt open in full . The phone has a light scrach which is less than 0.5 mm when i took it to the mtn store . The phone was booked in on the 8 of April . After 4 weeks of examination Samsung comes back and says physical damage , clearly this is a loophole or a scapegoat for them not to replace my phone . Today is the 30 of May 2023 and I am paying for a phone that I dont have . Absolutely disgusting service Samsung .
