Ignores me and won't come fix their errors

According to their Facebook About Us: "Small family business that has been in the home improvement industry for more than 30 years". They came to put in 2 of my doors on 15 August 2025. It took them 7 hours to remove 2 doors and put 2 doors in. I had to work so I left them at my house to continue their work. When they were done, I immediately paid them the R2300 they charged me. When I got home from work, I saw that they put both doors in upside down 😂 they removed the broken doors so they would have been able to see how they were supposed to be. When I contacted them the same day, they said they would come and fix it on 18 August. I have been following up with them since then. They constantly have excuses why they can't come and fix their mistakes. They just ignore my messages and phone calls. I have given them ample time before I give bad reviews but they just ignore me. I have requested a refund as well. Very disappointed
