Test King support are NOT helpful. There so called "24/7 online chat support" is a joke. It is definitely not 24/7. When you email them for assistance, they obviously don't read it, because they reply with a scripted response. I am unable to use their products because I have a MAC laptop and no access to a Windows operating system, which is needed to use their products. I asked for a refund that they have given me the run around rather than refund my money. I've sent numerous emails and have not gotten any help. I will NEVER use Test King. They are a total rip off. They are quick to take your money and will offer you VERY little assistance when you are not able to use their products.
