Worst service EVER

So my parents are building a court through 'Barrett's' who came 'highly recommended' via myself and more. The initial time given to build a court was up to 6 weeks. We are passing 12. Yes, 12! And the court is NOT done. Barrett's workers rock up EVERY day at 10ish, take a 'tea time' at 11' no shorter than an hour. Lunch is at 12! No shorter than an hour, and leave at 2:30. With very little work done that day. Then the rest of the time they are mostly lying around 'waiting for stock'. Apparently nobody knows how to pre-order. I have NEVER NEVER seen such a lazy bunch of people. When you talk to supervisors, workers, OWNER, everyone is always passing the buck, coming up with the same old excuses, Today they are 'waiting' again, and do not have stock of blue paint. 'maybe next week' he says. WHAT??? There have been NO rain delays til now, and today, yet again, they are lying around 'waiting'. So much needs to be done, but no capable/willing workers to do the job. This is just ridiculous. I have two more courts to build, and Barrett's will def not be the referral. If they are paid to sit around and work 5 min a day... they are surely fulfilling the requirements.
