Chefmate contact info?

My Chefmate mini-fridge abruptly stopped working. I've searched for their customer service info online and can't find anything for them or for the other companies that others have said are connected to them [C. Y. Top Ltd., Probus LLC]. I called Target [where I bought the product] and they have no manufacturer info for Chefmate. It's almost like they don't want to be found. Any ideas?
