Kerb Craft

I employed Kerb Craft to install lawn and retic to my back yard. The water coverage from the retic system was not covering the whole lawn. My wife questions this right after the install - but was told it was fine. It was not - and we had to hand water. Yes we tried adjusting the nozzle on the sprinklers! We advised Kerb Craft all this, with photos etc - and was told they would charge a call out fee. After repeated msgs over 6 months - they still have not come out and had a look. I would not recommend them at all!!!!
