Beamer is so support is a disaster

The Beamer is great and all in order, but only as long as holding the lamp. For me, the light fails to 700h and after 1.5 years. The projector was always at the same place and was operated normally. The warranty is indeed two years, however, only a year on the lamp. The beamer was then picked up at 29.04 with a pickup service and brought in a Czech workshop. Yes to deliver the notice from the technical support only the projector and accessories not was because this will no longer come back already strange enough. Now out of 5 June and the projector is still not back from the Czech workshop, namely in support (sitting in Holland) is someone accessible but they reached no one in the Czech workshop. The whole is now since 35 days, loaner will "of course" none asked why also. Number of Emails: 20 with no real success, number of calls 15, also not really successful, am curious how long it will take. Beamer had bought specially for the long lamp life given long, but apparently says nothing. For this reason, I have to say never again Benq, prefer a Epson projector which give eg 36 months lamp warranty.
