they refused to do a fixed price and said they only do pc which is fixed on completion, but at selections the consultant told us we were generously over quoted for the work they need to do... and our sales consultant said she did include the concrete for the crossover from the pavers to the road. so we expected it to at least break even to make up for things changing in price but for a 25% difference in price for an already over quoted price is crazy. but that's okay we will pay in the difference and have the paper trail questioning it all and depending on their answer we will let the ombudsman ask for invoices and have them explain to them why there is such a huge difference and why they did not take due care with out account. cause as we see it this means it was at least under quoted by 25% which for us would have made a huge difference if we could add this to our bank loan which we cant now! and this might also have influenced where we go to build our house, I have never heard of any one having this big a difference on a paving pc quote amount before. all we can think is someone messed up big time or the contractor charged for work not done, either way we want it sorted out
