Shoddy workmanship.

I had a roof installed on my patio after paying a 60% deposit. Firstly the colour was supposed to match my tiles - supposedly this is called Kalahari Red. It is fire engine/postbox Red. I sent Ronell a what's app with the picture. No response whatsoever. I then sent pics of the shoddy workmanship. Without any communication, a different team arrived. The first team had unnecessarily removed a pile of tiles from my roof and there were gaps everywhere. This team tried to fix the mess and did the best, but not on of them came to check. I wanted it over and done with and STUPIDLY paid the balance. That night when hubby came home, he flipped out and I messaged her again. No response. A few days later, it rained and water rain in to the bedroom adjacent to the lounge. Sent message request repairs and a quotation from another roofing coming which came to R6200 to.repair their mess. I requested that they return this amount to me. 3 weeks later I have still had no response, so will now be suing for the full amount of R24500 due to the bad workmanship and lack of communication. Ronell and Bessie just want to sell and do not care about anything else.
