Highveld computer STAY AWAY

I bought i computer a desktop computer the 4 th one from these people and the came and exchanged it last Saturday , i also bought a screen from them for R1100 rand which i had to pay double , yes they did give me back on of the payments after beginning, then the one pc they brought me last Saturday because the previous one crashed and i was to scared to ask these guys again so i got an IT person online to fix the computer i had to buy a new windows 10 R 3000.00 rand also the client i bough the screen for i had to write off R 10 000 rand in extra's i installed for him and also the money he still owes me because the screen looks terrible according to the client so i have lost almost R 16000.00 rand and all the stress and other work i could not do because i did not get this money in and the extra days i worked at this client just to keep him calm al because i trusted people , also i looked on line i could have bought brand new screens for R 200 rand more other people or company's charge between R550 and R650.00 for what Highveld computers charged me R1100 rand for and delivery charged with Uber of R250 Ashwell so i am loosing so much money and they caused me so much damage i will no recover from that , and now there owner Ashwin will look for reasons to blame it on ,me a person that knows nothing about computers and trusted them
