"I have subscribed their service for roof repair works 3 months ago. Sadly, there is no after-sales service. I have called many times to complain about the leaking that happens within few days from the repair work but no proper response or update to look into the problem. This is my worst experience with any contractor that I have dealt. Other contractors will entertain and relook into the problem and try to rectify it, especially if it is within few days of the actual work. Some even gives 6 months to 1 year warranty. But this contractor just don't bother to attend to customer"
