Renovation nightmare

Ashley Hoffman from Reds Construction was appointed to renovate and build 80m2 on my property. The initial completion time was supposed to be 10 weeks, and while there was some additional work (possibly about 2-3 weeks extra) ... 6 months later we still can't use the area.

Things that went wrong: - Has limited tools, his guys kept having to use mine - Has no transport, so he can't come to site to check up on the guys often enough - Laminate flooring had to be removed twice to redo floors as he can't screed floors - Requested payment without completing the roof, something I only found out later when I went up to look - Ripped the aircon unit out the wall by sitting on it - Had no measurements done for the fall of a major sewerage line which runs through my new build, requiring floors to be lifted and be chopped up again as the sewerage line blocks up. - Concealed cistern toilet needs to be chopped out for the second time because it's not straight - Doesn't pay his guys on time and they are unable to come to site because of no petrol/transport money - Forced him to remove the first plumber/electrician due to shoddy work, leaving us without water for 30 hours - Needed early advances throughout the build due to poor cash flow management - Guys often sat for hours on site waiting for materials. I often drove out to buy stuff just to keep the job moving - Last week he promised 7 different appointments for people to come to site to fix issues (plumbing, electrical, etc) of the 7 only 1 showed up - Today he said someone would come at 12, I asked him to let me know if they will be late and he said he would. It's now nearly 4pm and he's not answering his phone. - None of the plumbing is neat inside cupboards, so we would never be able to have a floating basin (with no cupboard) even if we wanted. - Everything he does needs to be double checked, hardly anything is ever level or even.

We have paid him almost in full as we didn't know the sewerage line was a problem when we paid him, I had to pay another plumber to come out with a camera to check for the problem. I've now appointed this plumber (who I'm paying) to oversee all the plumbing fixes that Ashley (hopefully) does.

We've now started fixing things ourselves and getting quotes from professional companies to fix things as I can't sit waiting day in day out for people to come and no one shows up.
