Extremely Poor Product and Customer Service Extremely Poor Customer Service. We had Bi-Foldind door installed with Chrome handles. Less than two years from installation the chrome handle developed bubbling. Reported to Zenith customer service and initially told by the Engineer that they would replace faulty handle. But no contacted us to arrange for the handle to be replaced. Made a complaint but no one from Zenith called back, even through a call back from management was promised on three different occasions. After 5 weeks I have now been told that the bubbling in the chrome handle is likely from weathering so they won’t replace it, even when the handle was less than 2 years old when the bubbling developed. Very poor excuse given and now told my Carefree policy does not cover this, although they had fitted poor quality accessory to the door. Even worse was the manner the customer service dealt with the complaint. Making promises and then no calling back. Anyone thinking of using Zenith for home improvement and taking out their carefree policy should stay away from them.
