First thing, they sent out the wrong color. So we had to wait an extra month before they could start. We had installed (2) patio's. 4 months later, I noticed rust starting to form on all the base supports. I called Hausner front office and I explained our problem. They wanted pictures of the support bases. I sent Melissa pictures, she said she will get back to me in a couple of day's. I waited 7 days called back and got another girl who was rude and said Melissa was out. I asked Melissa would return my call the next day when she returned. Another week went by, no call. Finally, the 3rd week, I called again and got her. She was extremely rude also, stating they do not warranty materials supplied by their installation team. I reviewed their website, and it states lifetime warranty. Also, they state that all materials are powered coated. I called for the 4th time and asked to speak to the owner, Melissa told me they are out of town, and she will have them call me in a week. It has now been 2 weeks since I have not heard anything.
