Now, more than 4 months passed by together with a couple of phone calls and emails with Xerox Support. All they said is they look into it. However Xerox keeps silent since a couple of months by now. A status request via email some 4 weeks ago went unanswered. Xerox does not answer.
To all Xerox employees and responsible persons as well as to all members of this community -> THIS IS ABLOSUTELY UNPROFESSIONAL BEHAVIOR OF XEROX.
