I ordered a computer case with a viewing window from Zalman. When I took the case out of the box I noticed the viewing window had a large blurry defect the middle of the window. I've filed multiple RMA's, sent multiple emails to multiple Zalman support address, attempted calling their phone support number multiple times and I've been ignored in every instance. When I post on their Facebook page they delete my posts. This problem has been ignored by Zalman for over a month. I've been posting on forums and product review pages about my negative experience and intend to keep it up until they fix the problem they are responsible for. Zalman has absolutely horrible support. Zalman doesn't care about their customers at all. I feel Zalman scammed me. Never do business with Zalman.
