are you facing the same issues bro? I have complained to them twice. They came with two different installers (different from my original installer who have installed my doors) to repair when I have complained to them on the jammed shaft issues, my second door are unable to open as the shaft were stuck inside the hole. They want to charge me for future repairs after my one year warranty end. This is obviously a design failure, whereby the hole of the door frame have obstructed the inner hole and the shaft are unable to go in and go out smoothly.
