From a reasonable start for a couple of years, DTS-NET lost my whole site, and after that were always pretty useless and definitely evasive. Since the site has shown any kind of content (their holding screen) I have been unable to log in at all. Despite a number of tickets being opened with their 'help desk' they just close them down without ANY communication.
Luckily, I held my domains elsewhere, so haven't been inconvenienced as some others appear to have been.
I would strongly recommend that you keep well away from DTS-NET if you would like a reliable online presence!!
