My builder do not care at all about the traders on there, i had a scenario where i got shortlisted, I immediately recognised the details of a customer I was already in a quoting process with. I contact my builder to ask them to cancel it off within around 3 min of being shortlisted. It was tough luck, pay for it anyway. Clearly they put more stock in just taking money than providing a fair service. Knowing full well that that lead has not helped me in anyway, they are still happy to take my money, says a lot about the companies ethics and the people who run it.
