Bad service at Makro Silverlakes and DELL

I bought a laptop late February at makro Silverlakes, I started using this laptop in March only to find that the space button does not always respond when I press it and this laptop is giving me error messages when I install my working software, this thing doesn’t want to install my printer drivers. I since came from site just before the lockdown and couldn’t drought my work because that is what I bought this laptop for, I had to pay R 11 000.00 for someone to drought my work for me on top of the R 17 000.00 that I paid buying this nonsense laptop. I took it back during the lock down, they refused to take it back because they did not open their returns department so I took it back today but they told me that there is not technician to assess it, instead when I voice out my frustrations they told me that I am harassing and I am a nuisance to their white customers and then called the police to come and arrest me. I run a business and I am also a Masters Student, I do not have the time for them to take the laptop for repairs because as it is, I have lost a lot of money and I also have assignments due next week Monday and Tuesday and throughout the month of May and June I am writing Exams, I have to research on online to do my school work, I have to attend virtual classes and meetings and they want to see me without a laptop. I cannot lose money because of the lockdown and lose money because of makro and also risk failing my studies, I am paying money to for my studies. Makro nyana e e nyako mpona ke sena selo! They want to see me and my family impoverished. This is my first and last time I am buying a DELL laptop/ Computer and buying a laptop at makro and I will never repeat such mistake again. If you want to receive the worst service ever, go to Makro silverlakes, they must just give me my money back, makro is not the only shop.
