Did not do the survey properly

Mike Jennings came out to my property 28/07/2015 and did an evaluation/survey of work that needed to be done. I received a quote 29/07/2015 and responded to his Quote notifying that the prices looked good and that I would confirm at a later date. 18/8/2015 I phoned and left a message on his cell phone notifying him that I accepted the quote and how he wanted to proceed. He emailed me his bank details requesting 50% upfront. Payment was done 18/08/2015 and proof emailed to Mike. Work commenced 22/07/15. This took 2 days and was not happy as it was not completed properly. He sent his guys out again to finish the painting. He then queried the balance of payment and I asked him about the black strip that was not removed. He said he left it but will monitor once the first rains start. I paid the balance 28/8/15 and sent him proof. I called him 08/10/2015 after the rain flooded my garage again. He said he will come out when it is raining again to see exactly where the leak was coming from. After some heavy rains I tried to call MIke, 17/11/2015. eventually spoke to him and he said I must approach my neighbours to have the problem fixed from the outside. Stopped responding to my emails.
