Frustrated

I bought a laptop at Hi online and it was delivered on the 29th of January 2019. On the 21st of Feb it would not power on. I took it to Hi Menlyn and was assisted by Ashler who at first was a bit skeptical about hearing my story of how important the laptop is to me because it is my working tool that I use on a daily to see clients. My first issue was having to insure this laptop which was a nightmare, posted on Hi’s Facebook page to assist, but nobody cared to assist until I went to the store. I left the laptop at Hi Menlyn without being given a ref number. It has been 4 days and I haven’t heard anything from the store about the progress. I haven’t even used this notebook for a month and already I’m having trouble. I want a credit and will buy a notebook elsewhere because I am now losing clients due to this.
