I bought an Arneg Santiago couple of years ago and is still under warranty. We had a few installation problems that were sorted fortunately. But recently i have been chasing Jordon support to fix the sliding doors and it has been six months and they sent an engineer about 4 times after constant chasing. All they do is have a look take pictures and go. The doors are now very difficult to slide and my customers are complaining everyday. I don't think Jordon group wishes to fix it.
Very unhappy.
