RTH services

Rael from RTH waterproofing services waterproofed parts of my roof in October 2024. I have a flat roof and I live in a very wet part of Cape Town. He promised me that his rubberised product was virtually indestructable. Fast forward to this year and I am faced with multiple signs of water damage on my walls and ceilings. I phoned him many times. He eventually answered and said he would phone me in two days time. I have not heard from him since. He will not face me.He hasnt answered many more of my calls. I dont trust this business at all. The product was costlier than most and has not delivered what it promised.
