Extremely bad service @ Hemingwaus Hifi Corporation

I bought a laptop with Kifi copration in Hemingways, after few weeks of use I sent it back, the guy said he removed some apps that were making it slow after they kept it for an entire week, I took it back and I tried to use it but intead it wiped away all my work, I went back and the manager called Albertus said he is hoing to send it away to Lenovo after giving me the entire attittude. After two weeks without communication I went to the store again, the ladu calledTaschina responded to me thay she will call me when there isstill np communication, I left but they still nothing I came back 2 weeks later and Taschna just smiled at me and she went to check on her emails and she said they asked for a password which I gave them day one I left the laptop. I told them I am not going any where until they give me a proof that they have been following up on my laptop which they refused. Albertus the so called a manager in the shop told me that they will wait for from tje technicians. I ASKED for a laptop to work with and Albrtus said I can not get it, I then asked albertus for my money back which he said I will not get it back because there is nothing wrong with the laptop. I am sitting here @ Hemingways Hifi Corporation right now waiting for assistance and there is no help
