Appalling workmanship and service

I hired Genesis Construction to complete two projects in my apartment. Once the site inspection was done, I received a comprehensive quote and was pleasantly surprised at the level of knowledge by the contractor. Sadly, this is where the pleasant experience ended! The first project, which was kitchen tiling and the movement of one cupboard was promised to be completed in 3 days; it took 1 week to complete. I was constantly fed with excuses, delays, and poor communication. This all, even after I took 3 days off from work to be present for the commencement. Materials supp**** by Genesis Construction were short and insufficient for the project, I had to then purchase the additional items after hours. The cupboard was not built to spec to fill the space, it was hacked to allow for plumbing and pipes. The door could not close (no solution was provided) and was hanging on by two *****s. The area under the dishwasher and cupboard was note tiled. Shortcuts were taken in placing the dishwasher plumbing and pipes, this resulted in a 4-month leak, which rotted the cupboards, damped the walls, and gave rise to additional expenses for repair to correctly install. The lack of on-site supervision and professionalism made this a stressful ordeal. I had also contracted Genesis Construction to replace all steel frame windows to aluminum frames. Once again, the quote was comprehensive, and the contractor seemed knowledgeable. This is where all pleasantries ended! After weeks of promising commencement, I was fed excuses from load shedding, poor weather conditions, traffic, and delays at manufacturers etc. I was assured the framed were procured and they were ready to start. Many emails, messages and calls later, Genesis Construction was a no show and eventually cancelled the project from their side. It took two and a half months to get a refund, at which they still deducted 15% for a handling fee, after THEY cancelled the project. The contractor changed his number around early November without prior notification, this only led to more frustrations. One star is being generous!
