Technician service beyond bad

So here is the story, I took my Samsung to Samsung so they can fix it, gigantic mistake of my life. So the technician called me to let me know that they have replaced the screen but I couldn’t go fetch it because I had to go home. I told him I would come fetch it Feb month end and he said it’s fine. I went back month and he wasn’t around and none of the other Samsung employees could help me. I left and I went back again today to collect my phone only to be told that the removed the new screen because I was taking too long to collect it, I went there twice and both times I left without my phone. Apparently their policy doesn’t allow fixed phones to stay there longer and I wasn’t told that, I asked if I could fetch my phone month and they said it’s fine. But now all I’m hearing is stories, so I asked them to just give me my phone back unfixed and disaster. It looks like it was tramped on my a code 14 truck, it has scratches I knew were possible on a phone, it looks like someone else’s phone and they telling me they threw my screen away but how do you throw someone’s screen away knowing that you are going to strip the new screen off, like the hell. Anyway I am sitting here all ****ed off I can’t even breathe because this is too much, soul crusher. My advise is never take your phone to Samsung mall of Africa to be fixed because they just make it worse. They destroy it so you can be forced to pay.
