Don't Buy From nor Work for Cleanavent, Vacuvent, nor Clean Air By Design
These guys aren't organized at all, and have no morals. They fall behind on paying employees and sometimes never end up paying them. These companies are all within the same business owners. They take customers' money and never deliver products. I am sure they will continue to build "new" companies to "cover up".
I would say the persons behind these companies are professional scam artists and know exactly what they're doing. Their "business methods" are all to their favor and never to the customers'.
I think the law needs to investigate these companies a little deeper because it's simply not fair to allow them to run their so called business.
