Evetech Computer Store Centurion - Be very careful - They do not replace faulty computers

Bought a very expensive computer 22 December 2022. 3 months later mouse port stopped working. I have send computer to part serve for repairs. Paid courier costs. Took 4 weeks. Computer came back "all ports are working". Wanted replacement computer with Evetech. They refused. Wanted to send computer in again for repairs. Very unhappy. What about replacement policy and consumer protection policy.
