Bad work ethics and unreliable

I have paid Renier in March 2024 to repair a carport. We've provided the shadenet. We've paid him in full. The job wasn't done correctly and the shade net pulled away from the frame and at some places it came loose as the shade net teared due to not properly fitted. We've asked him several times to fix the problem. He eventually told us he will fix it on 1 July 2025. He never showed up. When we asked him about it, he said he's too busy and will pay us back. We've provided our banking details and asked him to also pay us back for the shadenet which is now damaged and cant be used. He told us that he will only pay us back when he get money in, with no indication as to when this will be.
