Other people from Germany have reported received their kit with no problems, so it sounds like you just got unlucky with customs. All you can do really is send it back, then have them try to send it you again, but it will be expensive for you in postage costs. I am from the UK and received my kit this morning, and that is 1 month and 2 days after I paid! A very long time shipping, but it seems to have got through UK customs with no problems, and I haven't even been charged VAT or import duty
I don't know if the kit is fully CE marked, but there are resellers around the world that sell this kit and I don't think it would get into Europe or the USA if it wasn't CE marked, but proving it may be difficult if not impossible... Good luck!
