Review Poor workmanship from Oubaas van der Linde Middelburg Mpumalanga

We added a on suite bedroom and braai area to our home. A project that was initially supposed to take 6-8 weeks took 7 months. The builder has no pride in his quality of work. He didn't answer his phone for weeks at a time. Another contractor and painter had to complete the work that he already quoted for and had been paid for. The roof is now leaking as well.
