Garage Door

In 2013, I called Iupac for a quotation on a double wooden meranti garage door. After paying the deposit, the installation was done by them. It wasn't even a month and the door fell. I called Iupac and explained to them what had happened. They had a technician there who said that the door must be replaced because the top panel split in two. After talking to the owner, he assured me that if it fell again, he would replace it. It was two months later and the door fell again. I contacted them again and they were there twice to take pictures of the style of door. When I spoke to the owner, he said that his supplier doesn't have that style of door and he is looking for a new supplier. I have called there a number of times to speak to him and he doesn't get back to me. When I spoke to the lady behind the desk, she said that he is not willing to pay for a whole new door that needs to be replaced.
