Poor Roof Maintenance

We had Louis Fourie rubberize/ waterproof our whole roof last year, at a hefty price. He provided good specs and promised to immediately follow up, any problems. Subsequent to this, there have been three leaks. He returned once, but didn't solve the problem. Following this, he's ignored my messages and refused to take my calls. I've now had to employ another professional to do his job, at our cost. He also has our house displayed on his website as a supposed success story. He needs to remove it immediately, unless he returns to redo the job successfully.
