Tracking number is not working

Dear IvoG,
I have received a DHL tracking number 10 days ago, telling me
„ Your items for Philips PicoPix Max - 1080p Full HD Pico Projector have shipped“.

But whereto?
The tracking number is not valid like for many other backers.
And if I try to ask BackerKit about a status,
I’ll get a note that they are bot responsible for shipping.

-> ???
