I just found this post randomly by searching google trying to get some answers about streamline web hosting! I find your experience spot on with what I'm having now, infact you are very lucky that they even responded to any of your support tickets. I have been using them for the last couple of years (for no other reason that they were the first I found and pretty cheap). I've had various problems and I've submitted about 7 support tickets, to date I have had not a single response to any, even when I threatened to just leave them and go with someone else. Halfway through my time with them they have just randomly added a site map link onto my website that is not in my own html, it just appears on the site once published and reveals all my hidden pages to anyone. I cannot get any control over it whatsoever and you guessed it, they just ignore all contact and don't respond to anything. I will back you up totally along the lines of they seem to promise the earth in support and professional service, but in actual fact it's like dealing with crooks that just take your payment and offer nothing but a bit of uncontrolled server space and no help.
