I have employed Cobblestone Driuveway and landscape from your site. I assumed they were rated due to their workmanship. Since I have had them start work they have tried to fob me off with all sorts of excuses about poor design and workmanship. As an example they broke a fould drain cover in my garden and left it in a dangerous state and covered with soil to hide the damage. They also fitted unsealed recessed manhole covers on my patio before laying the slabs meaning that the levels would be wrong where the slabs meet the covers. I am now in a position where I have to supply the correct manhole covers myself and also to decide if I want this shoddy company to continue with the laying of slabs on my patio, This is not a company that should be endorsed by any site for finding a reputable tradesman. What should I do?
