@ What are they selling?
We know they're not selling a "product", but they, well, *were* selling a "service".
Nothing wrong with that, except they misrepresented their service as being much more palatable than it actually was. There's the minor point that they outright lied about how the service was operating, coupled with disgruntled employees who let the end users know how wonderful employer/employee relations were going at the time, and you have yourself one company that's going down fast.
Of course, I'm quite sure there are other companies that do the same thing, but at least they can lie in a convincing manner, and more importantly, can keep the inner goings-on quiet enough that nobody cares.
So, it appears Spinvox management were a little less endowed in the brain department than most other management types...
