Horrible customer service

I bought a Samsung A04E phone brand new, after 2 months it went blank and switched it self off, I then took it back to the store for it to be repaired, they took the phone back then said i should come back after a month, then I went back after a month then they told me the phone has not been repaired yet and it has external damage, it's either it fell inside the water or i dropped it of which i didn't, they then said i should pay a certain amount in order for them to fix it, when I asked about the price they could not give me, they were telling me that Samsung has not rep**** in terms of the amount i should pay it's been almost two months now.
