Rubbish removal site clean up excavator and tipper hire

Dan did an absolute appalling job on our lawn. He did not cut it properly at all. The lawn is uneven, and there are still extremely long parts of grass in random patches of our back yard. He also left behind heaps of weeds. I was beyond upset and distressed at the state of our yard, we have actually not had our lawn looking like this before or by anyone else before. We tried to call him multiple times and he did not answer and we also text him politely asked him to come back. Nil response.
