Broadspec Epoxy

On the 29th April 2017 we have Robert Broadhurst arrived at our property to start laying an Epoxy Floor for us.
He started the Job and we were told it would take about 7 hrs to cure so we left the property and spent the night at a friends place, the next day(29th) we spoke with Robby and explained that we were not happy with it as you could not walk on the floor as it felt like sand paper ( no problem as he had to put the final coat on ) which we then paid him for the job thinking all will be okay, then found out it was polyurethane ?That night we spent an hour or more on our hands and knees pulling hair out of the floor as he had not cleaned the floor before applying coat! We queried it again as we still could not walk on the floor This application resulted in the floor becoming dis-coloured, patchy and looked worse than ever. We contacted Robbie who agreed it looked terrible and said he would put another coat on which he did. This still did not fix the issue. We are out of pocket for $$ and R Broadhurst has done a runner!!
