Zoethecus is out of business ?

Hi,
I just purchased a used z.4/r rack and a couple of the black phenolic support brackets which mount in corners to support the shelves were cracked. I tried by telephone and numbers unavailable and emailed customer@zoethecus.com and received it returned. I believe they are out of business. I spoke to local dealer today and he was contacted by zoethecus about a year ago and was asked if they were still having a demand for their products. They must have been checking the market before they made a decision to close. Thanks for any information, Don
