Champion Windows

Purchased 2 new patio doors with screens in Jan 2023. Had installed 3/27/2023. When we tried to use the doors the handles on the screens hit the locks on the Patio Door. One patio door would not lock and mechanism fell right out of the door. I understand if that issue happens, Champion needs to replace the whole door. The downstairs patio door is very difficult to slide closed (you need to be an adult to slide open and close the door and it doesn't lock. These issues have all been documented by Champion Windows. We we told it would be 4 to 6 weeks to get replacement parts. It has been 2 months and we are still waiting for our new screens and door. The manager here in Omaha NE "Mark" will net respond to text or phone calls. Have also reached out to sales people with no action taken from Champion Windows. Very disappointed in the service. I do have documentation and pictures of the issues.
