This company chose to not answer phone calls or emails, so I began to research who they are and where they are located. In doing so I found many mentions in suspicious looking business directory websites. Most of which this company claims to have been established in 2007 which is not true. I found out by using Google how to uncover website ownership and registration details using http://whois.domaintools.com, so I had a look at the information for my12voltstore and you can do the same here http://whois.domaintools.com/my12voltstore.com.
If they lie about this it just goes to show how dishonest they are and gives you an idea of what you may run into if you choose to buy anything from their website.
