Disgusting poor repeat workmanship by AwnMaster and lack of customer service

Unfortunately my experience with Awnmaster was not a pleasant one. They were contracted to install an awning for which they quoted , in addition this quote was a quote from them to install an isoboard ceiling, when they installed the isoboard ceiling the finish was sub standard and of poor quality and nothing like what i was expecting at all. I then got a quote from a 2nd company and was shocked to find out that awnmasters quote was in fact 4 times the price of the 2nd quote i received not to mention that the quote form 2nd supplier was for proper rhino board with cornices including a skimmed finish. I then contacted Awnmaster and requested they remove there sub standard iso ceiling, the 2nd supplier fitted there rhino board ceiling and the finish was superb and workmanship professional. 3 months later and i now have leaking issues which has caused damage to the ceiling and new cupboards that i had fitted . Upon contacting Awnmaster the owner Kevin was defensive and did not want to accept any liability at all and quite frankly was rude and unprofessional. He tried to blame the company that fitted the ceiling . i then contacted the ceiling company and they were extremely helpful and came out to site , i suggested that awnmaster be present at the same time of which they did. it was then discovered that the leaking was related to incorrect installation of awning and non existence of flashing , it was also discovered that there are gaping holes in the new awning. it has been 1 week and several attempts to contact them however they seem to not want to take accountability nor accept liability for damage caused. They only part they have informed me about is that they are coming to fit some custom aluminum piece. i have requested numerous times for formal response with regards to how they are going to solve the issue and the additional costs for cupboard damage etc. Awnmaster have a history as well, in that 2 previous jobs done by them i had to get them back to correct a carport they did for me which was not level and the use of tek *****s instead of pop rivets , there quote clearly indicated pop rivets . i would not recommend them at all
